I definately think carrying finger nail clippers would be a good idea for a medium to large kit. Or even for EDC. As for hair cutting, I would probably just use my knife to cut my hair short in a true survival situation. It might even make for a good tinder. I don't know as I've never thought to try it before. I can just imagine one of us walking into a barber and asking for a bag of hair, or somebody seeing the clump of hair in your altoids tin and thinking you're crazy. <img src="/images/graemlins/grin.gif" alt="" />
