I have a small Buck that I carry in my backpack to work. I hate it the metal is too hard and you really need a polishing stone or strop to work out the divots on the blade.

I have a Gerber that would keep a great edge forever but the peg that keeps it locked eroded easily so now it is a little on the dangerous side to use.

My favorite small bladed knife is a Alaskan cub bear caping knife but it is a sheath knife.
