ULTRA M9 bayonet [777be2] 1.0.0

M9 bayonet [777be2]​

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.

Design
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.

Some production runs of the M9 have a fuller and some do not, depending upon which contractor manufactured that batch and what the military specs were at the time.

Although it has been claimed that the M9 may be more prone to breakage than the older M7 bayonet, the M9 has a 20% thicker blade, the tang is reduced from (0.235 to 0.195 in (0.60 to 0.50 cm)) in thickness, and a 75% greater cross-sectional area of steel in the blade than the M7.
