"I don't carry a BUG. I do, however, have a blade at all times & spare mag when I carry."
Yep. That's me. No BUG, extra mag, knife. I've also got a belt Leatherman and a keychain micro-Leatherman, but the defensive potential of those are minimal. I may get me one of those little NAA mini-revolvers one of these days, though -- better than a knife in a last ditch, close contact range encounter, anyway. Really more supplemental to the knife, I'd never go anywhere (except to the airport, sigh) without the blade.
