I don't know either. I have a SOG multiplier in my BOB, and I EDC a Crosscut on my keychain. I've used it, maybe, three times. I usually have a pocket knife outside of work, and even then, maybe use it once every other day (for stuff that really doesn't need a knife, like the mail). At work, I don't carry anything besides my pen, wallet, keys, phone, stethoscope.

Obviously I'm still here.
