When you’re cold and wet and in desperate need of warming up you need a dependable way to get a fire started. The Gerber Bear Grylls firestarter is simplicity itself with one end providing a ferro rod to create a spark and the other a metal striker. There’s a lanyard running through both ends so you don’t lose track of anything and a powerful emergency whistle on that same lanyard that will allow you to signal for help. The whole thing tucks away neatly into a waterproof storage unit that measures a modest 4 ¾” in length. Mastery of fire is what separates us from wildlife. This piece of fire-related survival gear can ensure you walk out of the woods at the end of your ordeal.
Other newsletters and books followed in the wake of Ruff's first publication. In 1975, Kurt Saxon began publishing a monthly tabloid-size newsletter called The Survivor, which combined Saxon's editorials with reprints of 19th century and early 20th century writings on various pioneer skills and old technologies. Kurt Saxon used the term survivalist to describe the movement, and he claims to have coined the term.
This group is concerned with the spread of fatal diseases, biological agents, and nerve gases, including swine flu, E. coli 0157, botulism, dengue fever, Creutzfeldt–Jakob disease, SARS, rabies, Hantavirus, anthrax, plague, cholera, HIV, ebola, Marburg virus, Lassa virus, sarin, and VX. In response, they might own NBC (nuclear, biological and chemical) full-face respirators, polyethylene coveralls, PVC boots, nitrile gloves, plastic sheeting and duct tape.
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.
From the SpeedSafe, one hand assisted opening to the 4 position pocket clip to the uber-secure liner lock that prevents the blade from closing on your fingers the Brawler from Kershaw is the kind of safe, effective survival gear you want at your disposal when things get gnarly. The modified Tanto blade has a pointed tip for precision work, spearing or piercing and the high carbon holds an edge longer than standard carbon steel blades. An invaluable addition to your emergency supplies when the weather closes in and you’re miles from nowhere.
To me, the best option is to store emergency food. How much? If you have none, store enough for a few days. If you have enough for a few days, get enough for a week. How much you store depends on what time frame you think you're at risk for having to be completely independent. The early settlers of the southwest liked to store enough food for a whole year and still do to this day!
