Combat knife
A combat knife is a fighting knife designed for military use and primarily intended for hand-to-hand or close combat fighting. Since the end of trench warfare, most military combat knives have been secondarily designed for utility use (clearing foliage, chopping branches for cover, opening ammunition crates, etc.) in addition to their original role as close-quarter combat weapons, and may be referred to as "fighting-utility knives.
M6 bayonet
The M6 Bayonet is a bayonet used by the U.S. military for the M14 rifle, it can also be used with the Mk 14 Enhanced Battle Rifle as well M39 Enhanced Marksman Rifle. It was introduced in 1957, at the same time as the rifle itself. It is the only bayonet made for the M14. Like its predecessor, the M5 bayonet for the M1 Garand rifle, the M6 was intended to serve additional roles as a combat knife and utility knife. The basic blade design was like the M4, M5, and later M7 bayonets, based on the World War II designed M3 Trench Knife.
M4 bayonet
The M4 bayonet was introduced in 1944 for use with the M1 carbine. It was built on the M3 fighting knife. The M4 bayonet, like the M3 fighting knife that preceded it, was designed for rapid production using a minimum of strategic metals and machine processes, it used a relatively narrow 6.75-inch bayonet-style spear-point blade with a sharpened 3.5-inch secondary edge. The blade was made of carbon steel, and was either blued or parkerized.
Bayonet
A bayonet (from French baïonnette) is a knife, dagger, sword, or spike-shaped weapon designed to fit on the end of the muzzle of a rifle, carbine, musket or similar firearm, allowing it to be used as a spear-like weapon. From the early 17th to the early 20th century, it was a melee weapon used by infantry for offensive and/or defensive tactics. Today, it is considered an ancillary weapon or a weapon of last resort, although it is still used for ceremonial purposes.
