5 Ways to Sharpen a Blade Without Specialized Tools

We've said over and over that a good fixed-blade knife is central to any survival kit. Also, the key to any knife is that it must be sharp enough to cut through whatever material you're working on. In short-term survival situations, this is easy enough, since you can simply sharpen your blade at home and have it ready to use. In longer-term survival situations, however, even the sharpest and most durable blades will eventually dull and chip.

To keep your knife performing as it should, you may need to improvise and sharpen it in the field.

Editorial: YouTubers Drink Urine Through a LifeStraw & Embarrass Themselves

Since the invention of the video camera, humans have been using this technology to record themselves doing dumb things. Just look at the success of shows like Jackass, and you'll see that filming these dangerous acts can be a very profitable enterprise (as long as the medical bills don't exceed earnings). Of course, it's not hard to see that hurting yourself on camera can also result in lasting injury (and/or dead brain cells), so the paycheck doesn't exactly seem worth it to us.

Drinking urine through LifeStraw 5

Rhett (left) and Link (right) are the hosts of Good Mythical Morning on YouTube.

On top of this, filming and distributing stupid or dangerous acts might lead others to follow in your footsteps, no matter how many times you say “don't try this at home”. If you want to do something irresponsible, so be it—but at least try not to drag anyone else down with you. That's how we see it, at least.

YouTube Hosts Drink Urine Through a LifeStraw

Recently, we came across a video that demonstrates two popular YouTube hosts—Rhett and Link of Good Mythical Morning—drinking gross liquids through LifeStraws. Uninformed individuals may hear this and think, “the LifeStraw is made to purify dirty water, right?” It certainly is, but it also has its limitations.

LifeStraw Personal Water Filter

The LifeStraw filter removes waterborne bacteria, protozoa, and other dirt and particulates larger than 0.02 microns. We own several LifeStraw products, and have used them repeatedly over the years. These lightweight filters are quite good at removing bacteria and protozoa, so please don't think that our criticisms below have anything to do with the device itself. This is a clear case of user error.

However, like many other hollow fiber water filters, the LifeStraw does not remove toxic chemicals, heavy metals (such as lead and mercury), or viruses. These are all things that tend to be rare in natural fresh water sources, but can be found in water that has been contaminated by industrial byproducts or human waste.

Despite this fact, here are some of the things the hosts of Good Mythical Morning chose to drink through their LifeStraws on camera:

  • “Dirty” bath water (which actually looked pretty clean, to be honest)
  • Contaminated water from the L.A. river
  • Each other's urine
  • Water with cat feces in it

We'll reiterate: drinking piss, raw sewage, or industrial runoff through a water purifier is a REALLY DUMB IDEA, especially when it's done just for laughs. Don't ever try it.

Water purification pollution runoff

Contaminated water is not a joke, and millions of people die each year due to its effects.

If you'd like, you can watch the video below. In less than a week, the viral video (no pun intended) has already generated over 3.5 million views. However, we'd caution you not to imitate or encourage any of the behavior seen here.

The Play-by-Play

The video starts out tame, by drinking some dirty bath water through the LifeStraw. This is probably safe, unless the bathers have open wounds or extremely dirty skin. Rating: Probably OK

Next, the hosts drink water from the Los Angeles River, which is known to have a history of pollution (something the video hosts themselves are clearly aware of). Some might choose this as a last resort in a survival situation, but it likely contains traces of industrial pollutants and pesticide runoff that even the best filters can't remove. Water collected from a major city's drainage system may also contain traces of sewage, and therefore has a chance of being contaminated with viruses like Hepatitis A (although this is unlikely in the USA). Drinking this through a filter may be acceptable in a true survival scenario, but it shouldn't be your first choice, and it's certainly not something that should be done as a joke. Rating: Bad Idea

Drinking urine through LifeStraw 3

Then the hosts get to the main event: drinking each other's urine. Despite what you may have seen on some extreme survival TV shows, drinking urine is really stupid. Human urine has a high salt content of approximately 2 percent, compared to seawater's 3.5 percent. This number can rise dramatically as the body becomes dehydrated. Therefore, most sources (including the U.S. Army Survival Manual 3-05.70) recommend against drinking urine under any circumstances.

The only way pee might be worth drinking is after removing everything but the pure water through distillation (i.e. using an alcohol still or solar still). A LifeStraw cannot possibly remove things like the high levels of salt, uric acid, and other chemicals your body is trying to get rid of. Drinking substantial amounts of urine—even through a LifeStraw—can lead to severe dehydration and organ failure. Rating: Extremely Bad Idea

To verify these statements, we reached out to LifeStraw's parent company, Vestergaard, for a response to this video. Meryl Rader, communications director at Vestergaard, had this to say:

“LifeStraw does not remove dissolved salts and was not designed to be used to drink urine. It was designed for natural disasters and removing pathogenic, microbiological contaminants from water.  Drinking urine, with or without a LifeStraw, is not something that we encourage. Whether or not drinking urine in small amounts is high or low risk is a question best asked to a physician.”

Drinking urine through LifeStraw 4

Finally, the pièce de résistance from this video: cat feces in water. This water is guaranteed to contain a variety of bacteria and protozoa, which should be mostly removed by the LifeStraw. However, it could also contain various harmful chemicals and inorganic solids, or even the Rabies virus (which is unlikely, but has an almost 100% fatality rate if contracted and left untreated). Since the solid matter in feces is 25 to 50 percent bacteria by volume, they're basically drinking a microorganism smoothie to see what happens. Brilliant. Rating: Bad Idea

What Can We Learn?

The moral of the story is that the LifeStraw and other water purifiers are not toys. Just like you wouldn't go play Russian roulette with a loaded revolver, or juggle needles loaded with infectious diseases, you shouldn't play around with a device that's designed to protect you from serious illness. You certainly shouldn't use it improperly on purpose, and you absolutely should not imply to others that this is acceptable behavior.

LifeStraw Personal Water Filter in use 2

Look, we're not trying to be buzzkills here. We get that this YouTube channel is all about fooling around in a humorous manner, and we don't usually have a problem with comedy videos. However, this is a video that has been seen by millions of viewers—many of whom are likely too young or impressionable to know the danger of imitating its content. It lacks an adequate warning about the real dangers of drinking dirty water, and to top it off, it's (jokingly) posed as survival advice by the hosts:

Rhett: “We asked you to ask us questions about survival, because we know how to survive around here.”

Link: “Yeah we do!”

At the end of the day, it doesn't seem very funny to drink contaminated water as a joke, when waterborne diseases are the number one cause of death worldwide according to the World Health Organization. In our opinion, it seems distasteful, and it makes a mockery of those who need to use products like the LifeStraw to stay healthy.

It's also already causing misconceptions about water purification to be spread by other web sites. Don't take our word for it, just look at this Attn.com article titled, “Invention Allows You to Drink Your Pee Safely”. Despite the obvious scientific fact that a LifeStraw does not make urine remotely safe to drink (and was never designed to do so), this video has directly resulted in the spread of this dangerous claim online, and that's truly unacceptable.


Infographic: Cloud Identification & Weather Prediction

Whether you're hiking in the backwoods, sailing out to sea, or simply enjoying an outdoor sporting event, it's extremely beneficial to be able to predict the weather. Of course, predicting it several days in advance has become a multi-billion-dollar industry, and skilled meteorologists can make big bucks forecasting the week's weather with high-tech satellites and radar. It's nice to have an idea what to expect in the next few days, but what really matters to a survivalist is the next few hours. Being caught unaware by a rapidly-approaching storm can result in hypothermia and may even put your life in danger.

A quick I.D. guide to some of the most common cloud formations.

Fortunately, you don't need access to the Doppler 9,000 to identify incoming weather patterns in your immediate vicinity. You can use a method that has been practiced since the dawn of time: reading the clouds. See the infographics below from NOAA and NASA, for a photographic guide to cloud identification. (You can click the image and use the “Download” button in the top right corner for a larger version.)

Cloud identification weather prediction 3

Obviously, there's a lot of complexity to cloud formation, and this subject can be confusing at first. As a general rule, clouds grow larger and sink lower as they build moisture, so watch how high-level clouds in your area develop over time. Most of us have seen the anvil-shaped Cumulonimbus clouds that lead to thunderstorms, so those are an easy type to watch for.

This Youtube video also does a good job explaining the concept of cloud identification and how it relates to weather:

So, to summarize:

  • Both cold fronts and warm fronts can bring rainfall, but cold fronts are generally more severe.
  • Cold front storm development: wispy high-level Cirrus clouds, rippled high-level Cirrocumulus clouds, mid-level Altocumulus clouds, low level puffy Cumulus clouds, building into larger Nimbocumulus clouds (occasionally anvil-shaped).
  • Warm front storm development: wispy high-level Cirrus clouds, high-level layered Cirrostratus clouds, high-level hazy Altostratus clouds, sheet-like lower Stratus clouds, darker Nimbostratus clouds.

William R. Forstchen Interview

In 2009, Dr. William R. Forstchen's One Second After took the world by storm. Equal parts thriller and cautionary tale, it was cited on the floor of Congress as a book all Americans should read. For those who somehow missed it, the book examines the aftermath of an EMP (electromagnetic pulse) weapon being detonated in the United States. In literally one second, virtually all electronics are rendered useless.

In the novel, John Matherson — a retired U.S. Army colonel and professor of history at Montreat College in North Carolina — reluctantly steps up to lead his community in the wake of this horrible disaster. One Second After realistically portrays both the good and the bad that would be associated with such a cataclysmic event. It became an instant classic in the prepper world.

The long-awaited sequel, One Year After, recently hit book shelves and is available on all e-book platforms. Forstchen graciously took time out of his busy schedule to discuss the realities of an EMP attack, how his best-seller changed his life, and what we can expect from his latest work of fiction.

OG: Every author hopes their work finds an audience with whom it will resonate. When you were writing One Second After, did you have any inkling of just how popular it would become?

William R. Forstchen: No idea whatsoever! By the time I wrote One Second After, I had published over 40 books, mainly in the field of science fiction. But after completing graduate school with a Ph.D. in history in 1994, I was shifting more into history, and military history. I had reached a comfortable level as an author but — other than the books I had coauthored with Newt Gingrich — had never, with just my name on the cover, hit best-seller status.

I actually wrote the book before “taking it out” for publishers to look at. Around 10 or so publishing houses rejected it, until finally Tom Doherty at Tor/Forge took a second look and decided to go with it. So from the time I first started writing until the day it hit the book shelves was over five years. It was the shock of a lifetime when, two weeks after the book was released, my agent called with the news that we had just hit New York Times best-seller status and the book was off and running.

It has been about six years since One Second After was first published. In the time since, the book has been cited on the floor of Congress as well as used as a cautionary teaching tool across the country. Do you feel the United States has made any significant progress in terms of EMP hardening?

WF: This is definitely one of those “yes and no” type answers. My hope was that the book would arouse interest at the federal level for two major actions. The first to begin a serious effort to at least “harden” some of our infrastructure from the threat of an EMP or CME (Coronal Mass Ejection) from the sun. Second to start, as was done back in the 1950s regarding nuclear war, a campaign of national preparedness, meaning public information, training of military and government personnel, and stockpiling of supplies. And third, to encourage a more robust foreign policy to prevent potential enemies willing to use nuclear weapons from obtaining those weapons.

The federal government has failed on all fronts. I am appalled by the lack of action in Congress and by an executive branch that has failed both with North Korea and Iran to make abundantly clear that even the remotest kind of threat will never be tolerated. America could and did recover from Pearl Harbor and Sept. 11 — recovery from an EMP strike is impossible. There will be no second chances.

The “yes” side of my answer? I have been amazed by the response of “we the people,” even while the federal government is moribund in its response. Millions of ordinary citizens are taking the threat seriously and preparing. I disdain how media tends to portray preppers. I have attended dozens of conferences since the book was published and have found the ever-growing prepper movement to be made of Americans who believe in self-reliance rather than wait for the government to do something first. I see them as the hope of the future.

From your perspective and research, what are one or two things you feel we as a country should be doing in terms of getting better prepared for an EMP threat?

WF: Every citizen should be prepared to provide for themselves and their family for up to a year after such an event. It is good common sense, which applies not just to an EMP, but also to a major solar storm, a Katrina-level hurricane, a serious financial collapse. Preparing is just plain old common sense.

On the federal level? If I could chose but one thing, it would be a robust foreign policy that made abundantly clear to Iran, North Korea, and their potential surrogates that we will not hesitate to strike first if we suspect a move toward hitting us with an EMP. An EMP is a first-strike weapon that, if used against us first, will be a blow this nation can never hope to recover from. The Congressional study of 2004 stated that the fatality rate would approach 90 percent after one year. We are not talking about 3,000 dead as witnessed on Sept. 11 and also on December 7th. A major EMP strike would be a near extinction level event for the United States, and our federal government has utterly failed to treat it with the seriousness required.

What was the impetus behind writing One Second After? Did research lead you to the story idea or was it the other way around?one-second-after

WF: I was in Washington D.C. on the day the 2004 report on EMP was released and saw the complete non-reaction of the mainstream media and the rest of government. I later spoke with the chairman of that committee, Congressman Roscoe Bartlett, who lamented that the problem was that the issue of EMP lacked a constituency of voters who took the topic seriously. He then urged me to write a popular novel to try to get the word out. That was the original motivation, then fueled by the research the work required and the realization on my part of how vulnerable we are to this threat.

My inspiration came as well from some of the great classic cautionary tales of the 1950s and '60s, such as Alas Babylon, Fail-Safe, and the truly frightening On the Beach. Those books helped to awaken and move public opinion, and I owe an acknowledgement to those works.

Without giving away any secrets, what is the basic storyline of One Year After?

WF: [Smiling.] As the title implies, it picks up the storyline a year after the end of One Second After. It presents two plotlines, the first being how to start rebuilding infrastructure, and even more importantly, how does America start to rebuild itself as a nation. Do we do so from the top down under the aegis of a renewed federal government, or from the bottom up of local communities reuniting?

Did you always plan to do a sequel to One Second After?

WF: Definitely not! I resisted for quite a few years. It was a highly disturbing storyline. I use to joke with my daughter that someday I was going to write a book titled Happy Bunny Goes to Town — seriously I really did want to write a happy children's book! I did have the pleasure of writing a book in cooperation with NASA, Pillar to the Sky, which presented a positive vision of a renewed space program. But always I was being asked to do a sequel to One Second After and finally I could no longer say no. That and enough time had passed that even in my own mind I found myself mulling over just how we might rebuild and what political and military challenges would then be “out there.”

Your hero, John Matherson, is a history professor at Montreat College. You are a history professor at Montreat College. Is that as far as the similarities go between you and your protagonist?

WF: We both teach at Montreat. I have one daughter who became something of a model for the two daughters, though a difference I thank God for is that my daughter's health is exceptional. But as to who John is, I modeled him after a dear friend, a retired WWII general who passed away just as I started to write the book, and several other veteran officers — men who, after the experience of war, sought to live lives of peace, but in a time of crisis could rise to the challenge. So many characters in the book are based on real friends and neighbors. I hope I did them justice because Black Mountain and Montreat, North Carolina, stand in my mind as the best of what America was, is, and will always be.

Novelists often mention how their characters seem to have a life of their own. Did any of your characters end up doing something that surprised you or perhaps took the narrative in an unexpected direction?

WF: There were moments of plot turns I had not anticipated. Two of the most difficult scenes to write actually involved John's dogs. I too owned Golden Retrievers and a Yellow Lab. When the moments came when the dogs played a major role, I had not anticipated writing about that aspect of post-EMP survival, but memory flashed of what happened during the sieges of Leningrad and Stalingrad in WWII. That was some very difficult moments to wade through, and since publication many readers have said those were the most difficult scenes to read in the book. Beyond that, part of the ease of writing the book was the fact that nearly all characters were based on people I know, and as the plot unfolded I simply had to write down how I would see them reacting.

Anything else you'd like to share?

WF: I still want to hope that not just my book, but others on the subject that have come out since my publication in 2009 will finally stir public reaction to demand a comprehensive and aggressive response by the federal government. I hope that protection and preparedness for an EMP or CME will actually be a serious issue in the 2016 elections. A presidential candidate, on either side, who states preparedness is one of their top priorities will most certain have my attention.

Everybody Loves a Good Story

Novels about the end of the world, or at least the end of the world as we know it, are especially popular amongst those who prepare for such things in real life. Not only do we enjoy reading about how folks fare after a major disaster, we can sometimes pick up new tricks and ideas to try ourselves. Many authors, such as William Forstchen, do extensive research as they craft their stories, working many real-world skills and bits of gear into the narrative.

Should you be in the mood for more world-altering destruction, here are a few suggestions:

The Ashfall Series by Mike Mullin

Alex is a teenager looking forward to having the house to himself for the weekend. His family is headed out of state to visit relatives. Unfortunately, fate has other plans and instead of a relaxing few days playing video games, Alex's world comes crashing down. The Yellowstone caldera, essentially a giant underground volcano, erupts and within days the entire United States is in disarray. What wasn't immediately affected by the blast is covered in feet of ash. Alex decides to make his way to where his family was heading and strikes out on foot. As the story progresses through three novels and one novella, Alex comes of age in a world irreparably and forever changed.

Hatchet by Gary Paulsen

A classic in every sense of the word, Hatchet has been thrilling readers for almost 30 years. Young Brian Robeson is flying to meet his father in Canada when his pilot suffers a fatal heart attack. After crash landing the plane in a remote lake, Brian is left on his own to find a way to survive in the wilderness. At his side is his only true survival tool, a hatchet his mother gifted him just prior to departing the airport. Brian spends almost two months in the wild, learning through trial and error how to survive. His adventures continue through another four books.

Pandemic by Yvonne Ventresca

Lilianna is 16 years old when her world is turned upside down. Both of her parents have jobs that take them out of town, and it's during one of those times that a new flu strain crops up and begins sweeping the glove. Called the Blue Flu, because it chokes off the victim's air supply, it's deadly and very infectious. Lilianna is something of a closet prepper, but she's far from ready for a crisis like this. As society begins crumbling around her, she's forced to reach out for help. Eventually, she teams up with several other teens in town to scavenge supplies as well as try to locate more survivors.

The Rule of Three by Eric Walters

EMP is the culprit in this trilogy. Adam is in high school, helping a friend with his homework, when the lights go out. It doesn't take long for folks to realize this isn't a normal power outage as vehicles, cellphones, and other technology have also gone dark. Adam's father, a commercial pilot, was out of town when the EMP hit. His mother, a local police captain, helps organize the community for safety and security. Adam's next door neighbor, Herb, is a retired government worker who turns out to be far more than he seems. Over the course of three novels, Adam learns just what it takes to survive in this new world.

The Weller by Adam Whitlatch

Some folks like wilderness survival stories, others are more interested in a community banding together sort of affair. For those who enjoyed the Mad Max movies, this one's for you. The Weller is full of gun battles being fought from muscle cars screaming through a desert wasteland. Matt Freeborn is the titular Weller, a person who can find water in a drought-stricken world. Time and again, though, it is his skill with a rather large firearm that keeps him alive.

Wake-Up Call by John D. McCann

The author is a well-known authority on survival and self-reliance. In this book, McCann's first novel, he utilizes fiction as a teaching aid. Todd and his wife, Melissa, are a relatively average couple. Far from anything resembling preppers, they are wholly unprepared for a massive earthquake that strikes their hometown. Utilizing an approach of, “Here's an example of what not to do,” McCann teaches the reader quite a bit about disaster readiness as the story goes along.


Emergency Dentistry: Where There is No Dentist

It's often said that nobody likes going to the dentist. It's not much fun to have someone poking and prodding inside your mouth with sharp metal instruments, especially when you've got to pay a hefty sum to have any dental issues taken care of. However, if you're stuck with a major dental issue like a broken or abscessed tooth, a skilled dentist is suddenly your best friend in the world. It's nearly impossible to go about your daily routine in excruciating, mind-numbing pain, and the dentist can quickly alleviate your suffering.

Like it or not, regular dental visits keep your pearly whites pearly and white.

Like it or not, regular dental visits keep your pearly whites clean and healthy.

In a SHTF emergency situation, it may not always be possible to simply go to the dentist. There may no longer be any dentists available, or those who are may be so busy they can't possibly help you. So, it's wise to have a basic level of knowledge about dental care and emergency treatment. This may make you squeamish, but it might be necessary to pull your own tooth or fill your own cavity to survive.

There's an excellent book available that can teach you almost everything you need to know about emergency dentistry. It's called “Where There Is No Dentist”, and it was written by Murray Dickson in collaboration with Hesperian Health Guides, a non-profit medical organization. This 200-page book is available for free through Hesperian's web site, so you can start reading it today without spending a cent. It's even filled with simple instructions and illustrations, since it's targeted at readers with no medical background.

Weekly RECOIL EDC: Monday Morning Mayhem

Even if you love your job, of us don't really like Mondays, because they mean the end of the weekend and the beginning of a new work week. However, the guys at RECOIL do what they can to brighten our Monday mornings with their Monday Morning EDC posts. These weekly RECOIL EDC posts show off different daily-carry gear setups, and discuss the reasoning behind these choices.

Recoil EDC mayhem 3

This week's RECOIL EDC loadout comes from contributor “John Darwin”. The author is using a pseudonym due to the fact that he has been working with a maritime SOF unit for over a decade, and must conceal his identity while he remains active duty. John is carrying a custom Springfield Armory Milspec 1911, an Emerson CQC-15, and a Surefire L1 Lummox flashlight, among other items.

For more details on John's EDC loadout, check out the full story on RECOILweb.com.

In the past, I've used these posts as an opportunity to showcase some of my own EDC gear. So, read on to see my weekday EDC loadout (photos taken yesterday).

Recoil EDC mayhem 4

Starting in the bottom left, we have a Gerber Diesel Multi-Plier in matte black finish. I normally carry a folding knife instead of a multi-tool, but the partially-serrated locking Wharncliffe-style blade on this tool is great for day-to-day use. The scissors and screwdrivers also come in handy.

On my keys, I have a Griffin Pocket Tool Mini, which I picked up at Blade Show earlier this month. It keeps my keys hooked to the edge of my pants pocket for easy access, and also acts as a compact bottle-opener and prybar (among many other functions). There's also a Sandisk 32GB USB 3.0 flash drive, which I often use to carry photos and work-related documents.

Recoil EDC mayhem 9

The First Tactical Medium Duty Light is capable of 274 lumens, and has an interchangeable bezel ring (seen here with the striking bezel). It also runs on AA batteries, which I usually prefer for a light that I'm carrying every day. They're a lot less expensive to replace than CR123s.

The watch is an old Fossil model, which has long since been discontinued. The sunglasses are Oakley Conductor 6s with grey polarized lenses. Not shown are my Otterbox-clad iPhone 6+ and brown leather wallet.

Emergency Cordage for a Survival Bow Drill

Although most of us already carry paracord or rope as part of our survival kits or bug-out bags, it's always wise to know where to find backup sources of cordage. There are obvious choices, like boot laces and lanyards, but some are less obvious. If you really think about it, you always have cordage on hand, even if all you've got is the clothes on your back.

Emergency cordage friction fire 2

Lonnie of Far North Bushcraft and Survival shows how to find emergency cordage.

In this video from Far North Bushcraft and Survival, the host demonstrates how to scavenge cordage from an old T-shirt's hem. The additional stitching and doubled-up fabric in this area makes for added strength, and it's easy to cut off without losing the protective qualities of the shirt. You might end up showing a little midriff or plumber's crack, but in a survival situation, that doesn't matter much, now does it?

Lonnie takes this T-shirt cordage, and twists it for added strength. Then, he incorporates it into a bow drill, which is an excellent friction fire-starting tool that we've covered here before. Considering the only other tools you'd need for this method are some wood and a knife, the T-shirt cordage could make the difference between a cold night and a crackling fire.

Emergency cordage friction fire 1

After hearing about this tip, you may think cannibalizing a T-shirt for cordage is an obvious choice. However, in a frantic survival scenario, you might easily overlook this resource, so it's good to be aware of. You can even use the sleeve and collar hems in a similar manner, without losing the warmth that the shirt provides to your core.

Of course, the bow drill is a great tool in its own right. To learn more about building a bow drill, check out our MacGyver-Level Pyro guide.


DIY: Making a Knife from a File

After spending several days walking through Blade Show, we have a renewed appreciation for those who make knives, especially when those knives are formed from unconventional materials. In the past, we've shown that it's possible to make a Karambit knife from a wrench, and Jack Stottlemire of Rustick Knives even made a Bowie blade from gun barrel steel. These techniques are especially relevant to survivalists, since we may be forced to work with found materials instead of buying whatever we need.

File knife DIY 4

So, here's another interesting DIY knife, modeled after the Japanese traditional blade called a kiridashi. The word kiridashi roughly translates to “to carve out”, and this straight-edged blade is similar in profile to a utility knife or X-Acto knife. These small fixed-blades were often used for detailed woodworking, bamboo carving, or even sharpening pencils. Traditionally, a kiridashi is beveled on only one side, but this modified version features a double-sided bevel.

File knife DIY 2

In the video below from Miller Knives on YouTube, the bladesmith demonstrates how to make a kiridashi knife from a file. Old metal files like the one in this video are often found in workshops and garages, and are typically made of carbon steel—similar to that used in many survival knives.

Watch the video to see how it's done:

It's not fancy, but it's simple and durable enough for frequent use. One downside is that bare carbon steel will need to be oiled occasionally to prevent surface rust, but that's true for many knives. We'd also consider rounding out the edges of the handle, or even wrapping it in leather or paracord, so it would be a bit easier to hold. Still, we really like the utilitarian aesthetic of this small blade.

Review: RoguePak Modular Hydration System

If you've ever used a hydration reservoir to carry water on the go, you'll know that these systems provide a convenient method of staying hydrated during physical activity. Rather than stopping, taking off your pack, and fumbling with a water bottle, hydration packs allow you to sip your beverage of choice through a long tube and bite valve. You don't even have to take off your pack or touch a zipper.

AquaPodKit emergency water storage 30

However, there's one flaw with traditional hydration systems: cleaning. They're much more difficult to clean than a water bottle. To clean a plastic reservoir properly, you'll need to drain it, wash the inside with water and baking soda (or use specialized cleaning tablets), and then hang all the components out for several hours to air dry. This process must be performed frequently, or the system may start to grow mold or bacteria that can make you sick. Even if trace amounts of mold in your pack don't make you sick, they can make the water you're drinking taste bad.

Speaking of taste, you need to be very careful what liquids you fill ordinary hydration systems with. Plain water is fine, but if you make the mistake of pouring in some flavoring powder or sports drink, the system may retain that flavor and smell forever. Don't even think about filling up with iced tea or juice, as these strong flavors will be near impossible to remove, even with repeated cleaning. To remove any residual taste and odor, you'll need to buy a new system (complete with hose and bite valve), since replacement reservoirs are usually not available on their own.

RoguePak Hydration System

The RoguePak and AquaPodKit are both made in the USA by parent company AquaStorage.

As a result of these frustrations with cleaning and lingering taste, a company known as RoguePak has developed a new type of hydration system. RoguePak is made in the USA as a division of AquaStorage, the same Austin, Texas-based parent company that makes the AquaPodKit emergency water storage system we previously reviewed.

The RoguePak modular hydration system allows what other hydration packs don't: replacing the reservoir at an affordable price. Every RoguePak system includes at least one spare reservoir, and the hose is fitted with a quick-disconnect adapter, so it can be swapped between the reservoirs in seconds. For $23, you get a complete system with one extra reservoir, or you can buy a 4-pack for $36.

The effects of this modular design are surprising, and they can actually change the way you carry water. So, we'll list some of the benefits we noticed during our testing of the RoguePak.

Advantage #1: Less Cleaning

Firstly, the modular design takes a whole lot of time out of the cleaning process. RoguePak reservoirs are reusable like other systems on the market, so you can still wash them out and fill them up again. However, having two (or more) reservoirs means you don't have to wait around for the system to air dry—you can leave one at home to dry out after cleaning, and fill another up immediately.

Advantage #2: No Residual Taste or Smell

Remember how we mentioned hydration systems tend to retain flavors and odors from the liquids inside? This is pretty much unavoidable, since the liquids dry into the seams of the reservoir, or seep into the plastic itself. Fortunately, replacing the reservoir eliminates both of these issues.

If the taste and smell isn't too bad, you can clean one reservoir thoroughly, while continuing to use the RoguePak with a spare. On the other hand, if the taste and smell can't be removed by cleaning, you can simply toss the offending reservoir in the recycling bin and buy a new one. The reservoirs are only about $5 each, with a four-pack available for $15 or $16 (depending on the capacity you choose).

Advantage #3: A Better Seal

Most hydration packs on the market today use a screw-on cap, positioned on the front of the reservoir pouch. To fill, you unscrew the cap, pour in water, and then tightly twist the cap back into place. A few others use a zipper that runs across the top edge of the reservoir. These designs seem fine, until you see what RoguePak came up with to replace them.

The RoguePak system replaces the traditional cap or zipper with a beautifully simple Fast-Fill port. Just pinch the layers together to create an opening, and fill with water. The port naturally flattens out and seals itself. Check out the video below to see how it works:

This isn't some TV studio magic—we tried this exact test with a RoguePak system, and it works as seen in the video, even if the bladder is filled to the max fill line and squeezed. To prove it really seals tightly, the RoguePak's inventor pumped it full of air until it burst:

Although the nature of the Fast-Fill port makes leaks very unlikely, RoguePak provides added leak-proofing via a Secure-Seal tube. Just roll the top of the port around the blue plastic tube, then snap the C-clip section over the top to hold the roll in place.

In addition to providing a leak-proof seal, this design keeps the RoguePak lightweight. It also eliminates the threaded cap and O-rings found on most hydration packs, making this design less complex and potentially less prone to failure.

Other Factors to Consider

At this point, some of you may be thinking that it's wasteful to discard reservoirs, or that the plastic materials may be harmful to the environment. Fortunately, RoguePak has addressed those concerns as well. Like we said earlier, the reservoirs are durable and reusable, so you could easily use them again and again to avoid waste.

Also, each RoguePak reservoir is made of LDPE, also known as low-density polyethylene. The particular LDPE material used by RoguePak is FDA and USDA compliant, Kosher, and has even passed a bio-toxicity report that indicated it can be used for medical applications. RoguePak reservoirs are 100% recyclable, so you can put them in your recycling bin instead of the trash can.

To top it all off, you can even burn discarded reservoirs as kindling. RoguePak says this LDPE material “burns as clean as natural gas”, so it won't produce highly toxic fumes like those from some other plastics. LDPE also burns slowly, so it can help sustain a fire until you add some larger logs.

Conclusions

We had a hard time finding any major flaws with the RoguePak. The biggest issue we noticed is that this reservoir is only designed with two round mounting holes, one on each side. This is fine for many backpacks, but certain packs—such as an old REI-brand pack we own—only offer one central hook for hanging hydration reservoirs. Another pack we have from Triple Aught Design has a central strap and two side straps, but these would require oblong mounting holes, not the round ones the RoguePak has.

If your backpack doesn't have compatible side anchor points, you'll have to rig up some paracord or small carabiners, or leave the reservoir loose in your backpack. Not a deal-breaker by any means, but we wish there was a little more adaptability here. Also, the flat profile of the Fast-Fill port makes air-drying a used reservoir a slow process, but that's a small price to pay for its various other benefits.

Overall, we were pleased with the RoguePak. It filled easily, didn't leak a drop, and provided reliable hydration when we needed it. On top of this, by throwing a second reservoir and some powdered drink mix into our bag, we could swap out reservoirs and re-fill with a flavored drink when we wanted to. Additional reservoirs weigh next to nothing—only 0.8 ounces each, according to our scale—and they can be rolled or folded into small spaces easily. RoguePak tells us the system is currently being tested by the US Army and Marines, and has received positive feedback as a result of these qualities.

Take one look at the streets of developing nations around the world, and you'll see that motorcycles are an economical and speedy way to get around, even when chaos ensues. On a motorbike, you can squeeze through tight gaps in traffic, out-accelerate most cars on the road, and tackle windy off-road paths that a truck or jeep could never dream of traversing. That's why a motorcycle makes an excellent bug-out vehicle, as we've said many times in the past.

However, as with any bug-out vehicle, it's crucial to keep your ride in good working order. The last thing you want is to pop a tire in the middle of nowhere, or to crank the key and have nothing happen during a real-life SHTF situation. So, knowing how to perform basic maintenance is strongly recommended. You don't need to be a master-certified mechanic to handle the basics.

This infographic from TitleMax shows the most essential motorcycle maintenance procedures, and how to do them yourself with basic tools. Check it out:
