I carry a multitool I've never heard mentioned here before; a Sears Craftsman. I originally bought it because I could easily replace it if something on it were to break, no questions asked. I've carried it religiously for several years now, and use it on a daily basis. It's never let me down despite some oft times hard usage. I like the fact that I can access all the tools with it closed, and the pliers can be opened one-handed once you figure out how to flick it open properly. I dearly wish it had a small flathead screwdriver, but I can't really complain. I also carry a Wenger 'Esquire' SAK on my key chain, which I mostly use for the scissors (I much prefer the Wenger scissor design to that of the Victorinox). Once in a great while I'll carry one of those surplus West German Army knives that have recently flooded the market; nice knives really, but a little bulky for my tastes. I have other knives and multitools, but I never seem to carry them on my person. They all reside in my glove compartment, BOB, or flight bag.
