Just a warning, but if you're buying that knife to use as a pocket knife, don't. It's a monster, and was not meant to be a pocket knife. It's no doubt a great knife, I've heard reports of it saving lives and such in Afraqistan, but is much too big to use as a pocket knife.
I also have an M16 and love it. I'd suggest one of them whole-heartedly if what you're looking for is a pocket knife.
