The wise outdoorsman always has a multitool with his survival gear just in case. They’re light, affordable, and in the case of the Leatherman OHT they’ll put the venerable Swiss Army Knife to shame. The OHT features needlenose pliers, spring action wire cutters, a high carbon blade, a serrated edge, a can opener, Phillips screwdriver, bottle opener and myriad other attachments.
For global catastrophic risks the costs of food storage become impractical for most of the population  and for some such catastrophes conventional agriculture would not function due to the loss of a large fraction of sunlight (e.g. during nuclear winter or a supervolcano). In such situations, alternative food is necessary, which is converting natural gas and wood fiber to human edible food.
DIY home surgeons will be excited to know epinephrine can actually be used with lidocaine (a numbing agent) to restrict blood vessels for faster wound repair. (Note: Cracked in no way condones performing self-surgery.) When sanitization resources become limited, the speed with which a wound can heal will have a drastic impact on survival rates. The longer a wound stays open and bloody, the more likely you are to get infections. Infections have historically been some of the most deadly and difficult-to-treat medical conditions, and even today they are not always easily survivable.
Again, the reason we tend to look sideways at those who get a little too into prepping for an apocalypse is because of their smug optimism. People actually being realistic about a dangerous future would be better served joining the military or ingratiating themselves with high-level government officials than agonizing about a little mouth scuzz or foot fuzz, right?
These people aren’t prepared because they’re truly passionate about survival — they’re really just very organized and have supplies on hand for handling everyday emergencies. For example, they might have a well-stocked first aid kit and a drawer full of flashlights and batteries in case of a power outage. These are great things, but in a true SHTF situation, they’re not enough.
People who are not part of survivalist groups or apolitically oriented religious groups also make preparations for emergencies. This can include (depending on the location) preparing for earthquakes, floods, power outages, blizzards, avalanches, wildfires, terrorist attacks, nuclear power plant accidents, hazardous material spills, tornadoes, and hurricanes. These preparations can be as simple as following Red Cross and U.S. Federal Emergency Management Agency (FEMA) recommendations by keeping a first aid kit, shovel, and extra clothes in the car, or by maintaining a small kit of emergency supplies, containing emergency food, water, a space blanket, and other essentials.
Bombs rain from the skies, alien ships descend with lasers ablaze, improbably proportioned, irradiated sea monsters tear through essential infrastructure. You'd think that running, screaming, and finding clean underwear would top the list of activities likely to improve your chances of living, followed closely by finding a sustainable food source and offering sexual favors to the person with the most impressive arsenal. Unless you were a prepper, in which case you'd be worrying more about the safety of your cigarette stockpile.
A: There’s a lot of overlap between the above question and this one but basically once you have your survival gear separated into different categories you’ll want to distribute it in the exterior pockets of the backpack where it can be easily accessed in an emergency. The MOLLE survival gear system devised by the armed forces for combat troops takes a modular approach to organization that’s also extremely flexible and allows you to configure your supply load in a way that makes the most sense for you. Rows of nylon webbing are distributed across a vest that’s worn under the backpack. You’re then able to attach various MOLLE compatible accessories and pouches – in this case containing your survival gear – to the vest. Additional pouches can be attached to webbing on the exterior of the backpack as well.
OK. Great. You've stockpiled for the end of the world, you quack. The chances of the world ending are smaller than ... holy crap, what the hell is a supervolcano? See why we're all doomed in 5 Ways The World Could End That You'd Never See Coming. And if that's not enough to get you to build your own bunker, check out 6 Tiny Mistakes That Almost Ended The World. Really, the planet almost ended due to a blown fuse? Come on humanity, let's get it together.
In both his book Rawles on Retreats and Relocation and in his survivalist novel, Patriots: A Novel of Survival in the Coming Collapse, Rawles describes in great detail retreat groups "upgrading" brick or other masonry houses with steel reinforced window shutters and doors, excavating anti-vehicular ditches, installing warded gate locks, constructing concertina wire obstacles and fougasses, and setting up listening post/observation posts (LP/OPs.) Rawles is a proponent of including a mantrap foyer at survival retreats, an architectural element that he calls a "crushroom".
Firearms instructor and survivalist Colonel Jeff Cooper wrote on hardening retreats against small arms fire. In an article titled "Notes on Tactical Residential Architecture" in Issue #30 of P.S. Letter (April 1982), Cooper suggested using the "Vauban Principle", whereby projecting bastion corners would prevent miscreants from being able to approach a retreat's exterior walls in any blind spots. Corners with this simplified implementation of a Vauban Star are now called "Cooper Corners" by James Wesley Rawles, in honor of Jeff Cooper. Depending on the size of the group needing shelter, design elements of traditional European castle architecture, as well as Chinese Fujian Tulou and Mexican walled courtyard houses, have been suggested for survival retreats.
The term "survival kit" may also refer to the larger, portable survival kits prepared by survivalists, called "bug-out bags" (BOBs), "Personal Emergency Relocation Kits" (PERKs) or "get out of Dodge" (GOOD) kits, which are packed into backpacks, or even duffel bags. These kits are designed specifically to be more easily carried by the individual in case alternate forms of transportation are unavailable or impossible to use.
In this review guide we’re going to shine a light on 21 essential pieces of survival gear everyone should seriously consider having in their survival pack. We’re going to concentrate on survival gear aimed at aiding those engaged in outdoor activities and not those forced from their home by natural disaster, although some of these products will also be useful in those types of situations. We’ll start by highlighting 3 pieces of must-have survival gear; those things we would not venture into the wilderness without, and then move on to other valuable survival aids you’ll want to think about packing.
