Let's see, I've got a Swiss Army knife in my pocket. I don't know the model, it's about the size of a Boy Scout knife. Two blades, screwdriver, bottle opener. I like the toothpick best of all really. I've got another bigger SAK in my "book-bag" that has some extra useless goodies with it. I almost never use it for anything.
I've got a leatherman tool on my belt that has a knife blade, and in the center consol of my Kia, I've got a Bucklite folder that's got a 3? 3 1/2" blade I guess. I don't really remember. Had it for years.
My only belt knife is one I had a fellow named Ben Shelor make for me years ago. I paid more for it then than I did for most of the guns I've ever owned. It's a good knife, but I hardly ever carry it anymore. I'll have to take a picture of it one of these days.
