Bayonet-knife

An edged steel item with a tapered point and a formed handle for overhand or underhand gripping. It is designed for use as a hand weapon, for general purpose use in the field, or as a bayonet when attached to the muzzle end of a carbine, rifle, or the like. The blade is less than twice the length of the handle and it is usually without a blood groove. See also bayonet.
