Close Quarters Combat Weapon System

The Combat Knife (UNSC CQCWS) is a United Nations Space Command infantry-sized knife.

The multi-purpose combat knife has a 20 centimeter (8 inches) blade made of high carbon steel coated for corrosion resistance and is 43.3 centimeters (1 foot, 5 inches) sheathed. All UNSC troops are issued with a combat knife for close quarters combat, for situations when ammo is scarce and is also balanced for throwing. It only appears in the novels and on the backs of ODSTs in Halo 2.

It cannot be used in the games. While some people believed it mayhave been a usable weapon in Halo 3, as it was on the chest of the C.Q.B Armor Permutations; Bungie repeatedly confirmed that the armor was only cosmetic in appearance.

ODST's
The only time a combat knife is seen is on the backs of Orbital Drop Shock Troopers, though they are never seen using it.
