I bought a Buck Crosslock about 1995. It was nice with a drop point bead blast blade that was extremely sharp. Not sure of the steel. I guess the pivot screw got loose and blade fell off. i could not seem to get the blade back on as there were washers that need to go back in but there were no room to do so. Sent it back to buck and they sent me a piece of junk buck odyysey with a dull blade. I dont think the warranty trade was any where close to being equivalent. I know the croslock was a used item but thats what the lifetime warranty should have covered.
