The Tardigrade: Nature’s Ultimate Survivalist

Posted on December 30, 2017 at 6:00 am.

As preparedness-minded individuals, we often consider what it'd take to survive dangerous or challenging situations — lack of food or water, extreme weather, manmade disasters, and so on. Unfortunately, despite all our brain power and physical dexterity, the human body is relatively weak and fragile. All it takes to end a human life is a few hours in hot sun or freezing snow without adequate gear. Even a small cut or puncture wound can lead to death in minutes.

Now, imagine if you knew danger was coming, and could simply curl up into a ball and go dormant until the situation was safe again. In this state, even a massive dose of radiation from a nuclear bomb blast, the frigid temperatures and vacuum of outer space, or the crushing pressure of the ocean depths wouldn't affect you in the slightest. Sadly, humans don't have this superpower — but there's an animal on earth that does. It's called the tardigrade.

The tardigrade, also known as the water bear or moss piglet, is a water-dwelling microscopic animal that has been found in virtually every environment on earth. Tardigrades are typically 0.3 to 0.5mm long — about 1/3 the diameter of the head of a pin — so they're not visible to the naked eye. However, they can easily be found by examining moss under a low-power microscope. They have segmented bodies with eight legs and a tubular mouth, which is used to feed on plant cells and small invertebrates.

The tardigrade's resilience comes from its ability to suspend its metabolism and go into a dormant state known as a tun. In this state, the animal can lose up to 99% of its water content and remain alive without access to food or water for more than 30 years. It also becomes impervious to temperatures approaching absolute zero, intense heat up to 300°F, pressure six times greater than the deepest ocean trench, and doses of radiation that would be guaranteed to be lethal to most other animals.

To learn more about the incredible survival abilities of the Tardigrade, and the scientific breakthroughs these abilities may someday lead to, check out the 4-minute video below from TED-Ed on YouTube.

Poll: Emergency Currency

Posted on December 28, 2017 at 6:00 am.

Written by Patrick McCarthy

In any emergency, short-term or long-term, it's essential to have liquid assets. We're not talking about potable water stockpiles, though you should have those too — we're referring to cash or other forms of easily-transferrable currency. Whether you need a little extra money for an everyday incident or you need to purchase some much-needed medicine after SHTF, you should never be without buying power during a disaster.

At the end of this article, there's a pair of polls where you can let us know your preferred types of emergency currency, but we'll start by discussing a few potential forms. This may help you rethink your options, or add a backup form of money to your disaster kit. It's important to diversify, and to collect an amount that's substantial enough to cover possible expenses.

Cash
This is the most obvious option, and one of the easiest. As the saying goes, cash is king… as long as the economy is still somewhat functional or will be in the near future.

You probably already have some bills in various denominations set aside in your bug-out bag or get-home bag, and that's always a good idea. Cash can come in handy for everyday emergencies, and it's accepted everywhere. You'll probably want at least a few hundred dollars, or possibly several thousand depending on your family size and needs.

After surviving two major hurricanes that wiped out his home, reader Bill Napier emphasized the importance of having cash on hand. Click here to read his story.

Cards
Credit and debit cards are powerful tools due to their high level of buying power under normal circumstances — if you need to drop $5,000 all of a sudden, a card is more secure than an envelope of cash. If your card is lost or stolen, you can cancel it or reverse charges, while you would have no such recourse with wads of cash. Some places, such as hotels, may require a credit card to cover incidental expenses.

For all these reasons, having an emergency credit or debit card set aside can be helpful in some cases.

However, these forms of payment rely on fragile electronic infrastructure. A widespread power outage would make these cards useless. Pre-paid gift cards are another option to consider, and unlike personal cards, they can be traded away for quick cash in an emergency.

Precious Metals or Gems
Gold, silver, and even gemstones are often regarded as a fall-back currency independent of paper money. However, there are some drawbacks. They don't have much intrinsic value outside their use as currency (or jewelry/decoration). You won't be able to walk into most stores and spend these like you can cash. Also, if everyone in your area is starving and fighting over basic resources during a long-term disaster, gold will become much less valuable than MREs, tools, or medicine — that ties into our next point.

Bartering Goods
This is a large category, and includes any item that could become desirable in an emergency. For example, antibiotics, batteries, gasoline, or ammo. Obviously, you'll want to stockpile extras if you plan to trade them away — if you only have one of a necessary item, you can't exactly spend it. Even alcohol and pornography could become valuable resources for trading in a post-SHTF situation, and you could use that to your advantage.

The downside to bartering goods is that you probably won't be able to use them under normal circumstances. If you don't know what we mean, go walk into your local WalMart and try to pay the cashier with something other than cash or card — you'll get laughed out of the store. That's why we'd classify bartering goods as alternative currency for emergencies only.

So, what does your emergency buying power consist of? Let us know in the polls below.

Infographic: 50 Animal Tracks of North America

Posted on December 27, 2017 at 6:00 am.

Written by Patrick McCarthy

While hiking, camping, or even walking around your own property, you may have come upon animal tracks you don't recognize. A few are obvious, such as the split hooves of deer or the thumbed feet of oppossums, but others may not be as clear. Understanding these footprints can help you know which species occupy your surrounding area, in turn making it easier to find food sources and avoid predators.

While you're not going to mistake a grizzly bear track for that of a horse, there are other tracks which can be easily confused with undesirable consequences. If you don't know what to look for, you might mix up squirrel tracks with that of a skunk and end up with a stinky surprise. Or you could think a set of mountain lion footprints are those of a dog — these prints are a similar size, but cat prints rarely leave claw marks.

The following infographic from Alan's Factory Outlet shows 50 different animal tracks from North-American species, and it's worth studying before your next outdoor trek. You probably won't spot most of these, but if you keep an eye out in the mud near streams or lakes, you might identify a few of the rarer animals in your area.

Catching, Cooking, & Eating Giant Grubs

Posted on December 26, 2017 at 6:00 am.

Written by Patrick McCarthy

In a survival situation, meal choices are not going to be between filet mignon and Maine lobster with drawn butter — menu options will be much more limited. Even if you're prepared with a backpack full of MREs and freeze-dried food, it's helpful to supplement your diet by hunting, fishing, and foraging. But at the end of the day, there may come a time when you need to eat something that's less than appetizing to stay alive.

Insects are eaten regularly by cultures around the world. While we may find the idea of chowing down on creepy-crawly bugs revolting, they can provide an excellent source of protein and nutrients. Also, they're often plentiful and easy to catch — you'll spend many more calories trying to catch a rodent or hunt bigger game animals. This makes insects an excellent survival food.

In the following video, [ shows how to catch and cook one particularly large type of insect: longhorn beetle grubs. These beetle larvae, also called roundheaded borers, can be found eating their way through tree trunks and punkwood. Hansler describes their flavor as “woody, smoky, kind of like a jalapeno popper” and says “I guarantee you I've eaten worse off the Chili's appetizer menu”.

To further enhance the flavor of the giant grubs, Hansler makes a dipping sauce from prickly pear fruit (also called tuna) and chile tepin (a naturally-growing form of hot pepper). The combination of spice from the pepper and sweet fruitiness from the prickly pear sounds pretty appetizing, even if its delivery vehicle is a bit less crunchy than a corn chip.

Video: Building a Siberian Log Fire

Posted on December 25, 2017 at 6:00 am.

Written by Patrick McCarthy

If there's anyone who fully understands the difficulty of surviving extreme cold weather, it's the residents of Siberia. This region of northern Russia is notorious around the world for its frigid sub-zero temperatures, and has served as a location for high-security prisons and Gulag forced labor camps due to its inescapable expanses of ice and snow. Even in parts of Russia with milder weather, the inhospitable conditions have contributed to the failure of multiple foreign invasions (including those of Napoleon and Hitler).

The military impact of Russia's cold weather on invading forces led to the nickname “General Winter”....

As a result of this hardship, Russians have come up with some pretty clever winter survival resources, from dugout shelters to off-road vehicles. We recently learned about another Russian survival technique known as the “Siberian log fire”. This structure uses one very large log and 5 to 7 smaller logs to create a fire that can burn all night with minimal tending or stoking.

In the following video from Far North Bushcraft and Survival, host Lonnie shows how he builds a Siberian log fire in an Alaskan forest. A large folding saw is used to cut down one thick tree trunk and five thinner trunks — a large woodsman's axe could be used instead, if no saw is available. These logs are stacked atop the largest log in a fanned-out shape, with the ends protruding slightly and almost touching each other.

The Siberian log fire is built on the ground beside the large log, and burns upward to ignite the ends of the others. Maintaining the fire then becomes as simple as adjusting the gaps and feeding the logs forward as they burn. Check out the full video below to see it in action and learn more about its construction.

Review: Spartan Blades Formido

About the Author

The founders of Spartan Blades, Curtis Iovito and Mark Carey, are two former Green Berets with a combined 43 years of military experience. Given this background, the duo formulated a straightforward objective: create blades that will meet the needs of professionals in the harshest environments.

At the New York Custom Knife Show, we stopped by the company's booth and noticed a new fixed blade on display. We weren’t the only ones at the table and this knife — known as the Formido — was drawing quite a crowd. Spartan has had a long-standing lineup of tactical fixed blades, and this new offering fits between the size of their Phrike and Enyo models. Loyal customers wanted to see what all the buzz was about, and so did we.

Shortly after the show, we received a sample of the new Spartan Blades Formido to test out, and we put it right to work. Read on for our full report.

Design and Construction

Starting with a bar of CPM S35VN, the Spartan Blades Formido is cut and ground to shape. For those of you unfamiliar with this steel, it comes from Crucible Industries, a leading name in American-made steel that makes Crucible Particle Metals (CPM). S35VN is a martensitic stainless steel that is designed to give the end user more toughness over another one of the company's popular products, CPM S30V.

We’ll skip the chemistry and metallurgy lesson, but it's worth noting that the added elements in this steel give it excellent toughness without a loss in wear resistance. This translates to better edge retention and less risk of edge chipping. We’re cool with that.

The boys at Spartan don’t spare any expense with their blade heat treatment and deep cryogenic processing. A lot of makers skip the cryogenic bath but the leading names in the business know the extra step is worth it to create even more wear resistance and durability. Again, there is a lot of science behind the Spartan Blades heat treat process, but rest assured, this attention to detail is necessary to create a blade that won't bend, roll, or snap under pressure.

After all the grinding, tempering, and quenching are complete, the Spartan Blades Formido is coated in one of the best coatings we’ve ever encountered on a blade. PVD, which stands for Physical Vapor Deposition, is the same coating used on many military machine guns and high-end firearms.

Spartan Blades claims this molecularly-bonded metallic compound will not stain, tarnish, chip or fade. Furthermore, it is extremely hard to scratch — the marks seen on our blade in these photos wiped right off. No exaggeration, our 4-year-old Spartan Blades Akribis folder (discontinued) looks brand new despite daily carry and hard use. We’ve beaten the snot out of it and you would never know by looking at the finish.

The finished blade combines clean computerized machining, a tough-as-nails finish and attention to detail in an extremely stout functional package. All corners on the Formido are beveled to dehorn the sharp angles. Even the weight-reducing triangular cut outs in the handle are chamfered for smoothness.

The blade has two subtle bevels below the saber grind; one from the plunge line to the belly and the other from the belly to the tip. These resemble traditional Japanese katana grinds but are not obvious unless you're closely examining the blade.

Carry System

The sheath of the Spartan Blades Formido is minimalist in design. There is a rolled plastic/Kydex insert surrounded by nylon. There's also hook-and-loop within the belt loop to reduce the size of the opening and prevent the knife from canting as you carry it.

Additionally, the guys at Spartan Blades designed the back of the sheath with a paracord grid that can be threaded in between PALS webbing for placement on a MOLLE-compatible plate carrier or pack. The retention on the sheath is provided by the friction fit against the blade, and there is a secondary retention strap that runs around the handle.

Overall, the sheath profile is sleek to prevent snagging on other gear. However, this also means its smooth front lacks expansion capacity for a pouch to house a fire starter, multi-tool, spare mag, flashlight, or sharpening stone.

In the Field

In case you’re wondering, the Formido will easily open up MRE pouches. We know you’ve read other reviews elsewhere where this may be the extent of cutting done. We stepped it up a notch knowing you deserve a much wider range of capabilities from a survival knife.

We easily cut through multiple layers of paracord, and then moved on to push cut through an old static rappelling line until the webs of our hands turned red. The Formido didn't struggle with either task.

Next, we used it for fire prep for campfires and our home fireplace when the cold weather settled in. This involved batoning through seasoned but frozen wood and making feather stick shavings to catch a flame. At first, we thought we scuffed the PVD coating, but after wiping it down with some water from our canteen and giving it a little finger rub, the discoloration washed off and the finish appeared untouched.

We tested the tip penetration capability by pounding the Formido through heavy rawhide, puncture-resistant Kevlar fabric, and aluminum cans. In short time, we were able to run the Formido through the gauntlet with enough eager friends wanting to see what it could do. Some were disappointed the Formido didn’t come with a sharp 90 degree spine for scraping a ferro rod, but others weren’t miffed by this.

From our experience with other skeletonized blades, we weren’t expecting the Formido to be our top choice for extended cutting comfort. That’s the reality of thin-handled knives and we know that isn’t the purpose of this one. We were able to get around any discomfort by wearing gloves, wrapping the blade in paracord (we liked the Crosstac Grip-Cord the best), or even adding some athletic tape.

With the way the sheath is designed, we were still able to use the button snap even with the handle cord-wrapped around the triangular cut outs. We ended up using blaze-orange paracord for a handle wrapping after we realized how well the flat dark earth finish of the Formido blended into the ground.

The Spartan Blades Formido was a pleasure to carry. We wore it on our battle belts and plate carriers, as well as in the field attached to our day pack's shoulder strap. The paracord lacing in the back of the sheath can take a while to get used to, but once it's laced up properly, it's not going anywhere. We found by dipping the ends of the paracord in fly-tying liquid cement (or your girlfriend’s clear nail polish), you can make the tips stiffer to push through the most stubborn MOLLE paneling.

The Formido disappears on your kit until you need it. To put the weight of the Formido into perspective, one of our loaded PMAGs jammed with 30 rounds of 5.56 ammo weighed in at 1.08 pounds while the Formido in its sheath registered only 0.49 pounds. It has a very slim profile — not quite as wide as an AR Mag pouch — and won’t get snagged easily on your rifle sling or other gear worn on your body while transitioning. Simply put, it’s a blade you’ll be glad you have on your person when you need it, but one you won't constantly be reminded of when it's not in use.

There is something reassuring about a knife with no moving parts. The Spartan Blades Formido gives the end user this fixed-blade strength for the weight of a tactical folder. Pair this blade with a good multi-tool and you’ll have an outstanding combination for the field. Mark and Curtis from Spartan intended to produce a blade meant for serious use in the field, and we believe they succeeded.

Pinhole Glasses: Improvised Corrective Eyewear for SHTF

Posted on December 22, 2017 at 6:00 am.

Written by Patrick McCarthy

If you had to give up one of your five senses, which one would it be? For most of us, eyesight would be at the bottom of the list. We rely on our sense of sight to walk, drive, read, write, recognize loved ones, and identify threats. If you suddenly lost your vision during an emergency, your odds of survival would undoubtedly be low.

Cell phone land navigation GPS map compass orientation 1

Learning to navigate blindly would be a real challenge during a survival situation.

Those of us who have poor eyesight know all too well how difficult it can be to go about daily life without corrective lenses — either glasses or contacts. In an emergency, these items can be lost, damaged, or become inaccessible. Disposable contact lenses will eventually be used up and thrown away. If you're prepared, you'll have backups of these items or will save up for laser surgery, but it's still wise to have a fall-back plan in case things really go south and you can't see clearly.

Unless you're a trained optician with a full set of working equipment, it's not exactly feasible to make a new set of lenses that match your eyes. However, there's another much simpler option: pinhole glasses. Instead of concave or convex lenses, these glasses use tiny holes to allow through very narrow beams of light, much like the pinhole camera you probably made in elementary school science class. This effectively increases depth of field and gives you sharper vision.

If you're curious about the value of this pinhole effect, you can test it easily at home. Just grab a sheet of dark paper and poke a pinhole through it. Then take off your corrective lenses and hold the paper with the pinhole just in front of your eye. Your vision will be far from perfect, but you should still see a dramatic improvement. More pinholes will allow in more light and provide peripheral vision.

Another method of testing this pinhole effect is to form a loose fist, and hold it up to your eye like you're holding an invisible telescope. Tighten your grip until only a pinhole of light is visible, and watch as once-blurry objects come into focus.

Like eyeglasses or contacts, pinhole glasses are only a temporary fix for poor vision. However, these are much easier to improvise in an emergency — just black out some cheap sunglass lenses and carefully punch some holes. You can even make them out of aluminum foil, as long as you don't mind looking like a low-budget version of Cyclops from X-Men. Either way, improvised pinhole glasses can give you a fall-back option in case your glasses or contacts are unavailable in an emergency.

Video: Visualizing Blood Loss

Posted on December 21, 2017 at 6:00 am.

Written by Patrick McCarthy

For those of us who don't work as emergency medical personnel, observing a traumatic injury can be completely overwhelming. Even if you don't freeze up or suddenly become ill, it's a natural human response to start to panic when there's blood gushing everywhere. This panic is amplified exponentially when the one who's bleeding out is a close friend or family member — it might even be your own blood splattering on the ground.

Fortunately, by preparing yourself mentally for this physical trauma, you can snap yourself out of the panic and take action. Even if there's a huge pool of blood surrounding the victim, there may still be time to save their life. The following video was posted by North American Rescue on Facebook, and shows a demonstration of just how much blood can be lost before the victim becomes disoriented or loses consciousness.

You may have heard that a typical adult body contains roughly 5 liters of blood — that's 10.5 pints. The instructor in this video demonstrates by filling five one-liter bottles with red liquid. As he pours out the contents, he describes what effects the victim will experience. When a full liter of blood loss has occurred, he says “it's bad, but not as bad as you think.”

Even after losing a full liter — that's 2.1 pints, or 20% of total blood volume — the victim should still be physically able to focus, assuming the psychological shock doesn't cause them to pass out. As blood loss increases past 1.5 liters, the instructor says vision will start to “tunnel in” and the victim may become unable to distinguish friends from foes.

Check out the full video below. It may help you keep some perspective if you ever witness a traumatic injury (or experience one firsthand). Of course, this also reinforces the importance of having a tourniquet on hand to stop the bleed ASAP. Note: This video contains some not-safe-for-work language.

Thanks to contributor Cameron Carden for letting us know about this video.
