The M9 bayonet, officially known as the M9 Phrobis III, is an American multi-purpose knife and bayonet officially adopted in 1986 by the United States Armed Forces for the M16 rifle. Featuring a 7-inch (18 cm) blade and issued with a sheath designed to double as a wire cutter, the M9 bayonet is designed to function not only as a combat knife but also as a multi-tool, capable of serving as a wire cutter, metal slicer, bottle opener, and screwdriver.
