A buck zipper has gotten most of the use the last severaly years. Very satisfactory. I've also had great luck with various gerbers and kershaws. I am a real fan of gut hooks--I no longer feel the need to pack around a wyoming knife. I prefer fixed over folding for a primary knife, but always keep at least 1 extra folder with me for Murphy's law. There's nothing like walking up on a downed animal to find your knife is back at the truck or atv a mile down the mountain!
