bayonet

A bayonet (from French baïonnette) is a bladed weapon such as a knife or short sword, or spike-shaped weapon designed to fit in, on, over or underneath the muzzle of a rifle, musket or similar weapon, increasing the weapon, as a spear. In this regard, it is an ancillary close-quarter combat or last-resort weapon. Some modern bayonets, such as the one used on the British SA80 assault rifle, can be used as wire cutters when combined with their scabbards. Knife-shaped bayonets—when not fixed to a gun barrel—have long been utilized by soldiers in the field as general purpose cutting implements.
