Having a decent cutting tool, I would say, comes in as #4 in the Five C's of Survival. Here, I am showing my choices for Every Day Carry (EDC) blades, as well as some primitive stone-age examples of how we as humans got to this point - so to speak....and a few of my choices for fixed-bladed and camp blades.
Having a big chopper is very importing when out in the bush for any longer length of time. A good solid full-tang heavy duty blade in indispensable and makes short work of many around-the-campfire chores.
Made famous by Dave Canterbury of Dual Survival TV show fame, the basic Five C's of Survival are:
1). Cover
2). Combustion
3). Carry
4). Cutting
5). Cordage
