I have a 440c cub and it is a GREAT knife! easy to sharpen, and I'm not afraid to hurt it. The sheath TOTALLY sucked (mine was the kydex one, not the newer thermoplastic spider-man looking one), so I took it apart and re-designed it... MUCH to success! All it took was a hair dryer, towels to hold the new molded shape while cooling, a drill, and the use of MAJOR calluses (sp?). nice knife...
