Alas, I will never have the good fortune to be able to make use of my PSK because I EDC the tools that would be in a PSK (folding knife, flashlight, whistle, et al) rather than put them in an out-of-sight/out-of mind kit. The problem I have with kits is deciding when the time is appropriate to open one up and actually use what's inside. "Is this an emergency?" With EDC user tools that isn't an issue; tools aren't for "survival" or "emergencies", they're users.

That said, BPJ's post about using the snare wire got me thinking about a consumables kit -- wire, string, duct tape -- not for emergencies but for daily use as required and then replace.
