I agree with climberslacker, great post and nice kit, thanks!

I suggest considering how this kit is to be used: what environment and situations we want the kit to address. The kinds of questions we might want to ask include: is it to fit every environment and situation? is it a wilderness kit? is it an urban kit?

Then we can examine kit contents against: (1) the Rule of Threes (you may die if you go: 3 minutes without air, 3 hours without shelter, 3 days without water, 3 weeks without food); (2) whatever set of survival categories you find appropriate (mine include: First Aid, Shelter, Fire, Water, Food, Navigation, Light. Signaling, Self-protection, Hygiene, and Morale); and (3) your other EDC.

I suggest working to set up a mini-survival checklist, preferably a computer spreadsheet.
