this i kwow is swiss because it has the + symbol below H.S.at the bottom of the blade right by the hand guard.the hand guard is marked with the # 57906. the + is also on the tip or ball of the metal sheath. the knife it self is slightly under 2' long the sheath is 20" the top edge of the blade is serrated or somtimes refered to as sawtooth. the tip of the blade flares out berfore coming to a point.the handles are of wood the button that releases it from the rifle is fully funtional. the thing is made from very solid construction and is overall in really good shape.I'm not exactly sure what rifle it goes on besides a swiss one. this is your chance to own this fine rather large edged weapon.
