Dave Canterbury first came up with the concept which he calls the 5 C’s (and the 10 C’s) of survivability. When putting together a minimalist basic survival kit, consider these basic categories for survivability. The most important are the 5 C's
Cutting, Combustion, Cover, Container, Cordage. Then add on the last 5 to make the 10 C's Candling device, Cotton Bandana, Compass, Cargo Tape, and a canvas needle.
