I'd be nervous about not having redundant gear nearby or at least available. That way you always know it's there, safe and sound, ready for your use.

My car kit has a USAF-style fixed blade knife and Gerber folder, the backpack kit has a Benchmade folder and Squirt P4, and the EDC is typically a Spyderco folder and/or Wave. Oh yeah, and a Swiss Army Knife in the camping gear bin. Probably a little overkill. If I really get in a tough spot, there's always the Lexan cutlery set. <img src="/images/graemlins/grin.gif" alt="" />

The vacuum sealer has done wonders for me not pilfering my own gear, too.
