Knives & Sharpening tools are worth mentioning on their own. Carbon steel knives are better than stainless. Sharpening stones are a must. Possibly the best all around knife you could ever buy is a high carbon steel Mora knife ($10 on Amazon with free shipping). The material is harder than stainless steel and they have a Scandinavian grind that makes them extremely sharp, durable, and even easier to resharpen than most knives.
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.
