I'll second the Fallkniven, or as an alternative the Cold Steel Master Hunter (4.5"). I have some great fixed blade knives, even an original Randall, but I now have a new criterion for my carry knife in most circumstances: sharpening requirements.

I use the Sterling Systems sharpener (see Doug's article) in most in-the-field circumstances. I wouldn't come near one of my valuable or custom knives with it, though! So I carry a knife I wouldn't mind using that sharpener on. Hard working "beaters"... not pretty knives,..but that's what I do.
