Combat knife

This article is about the UNSC weapon. For other uses, see Knife.

There is more information available on this subject at Combat knife on the English Wikipedia.

A combat knife is a knife designed for close-quarters combat. They are primarily used for trench warfare and boarding actions.^[1]

The Covenant use knives as well; the Jiralhanae use their own combat knives as well as a multitude of bayonet-like blades. The Sangheili sometimes use curveblades, which inspired the design of the Type-1 energy sword. The blamite-bladed energy cutlass is an analogous weapon used by the Kig-Yar.^[2]^[3]

Overview

Design details

One version of the UNSC's multi-purpose combat knife has a 20-centimeter (7.9 in) blade made of high carbon steel, an anti-flash, non-reflective titanium carbide coating, edge coated for corrosion resistance and is 43.3 centimeters (1 ft 5.0 in) long when sheathed. It is also balanced for throwing.^[4] The Spartan-IIIs' standard-issue combat knife features a self-sharpening blade made of a hyperdense material.^[5] Modern UNSC combat knives are made of strong enough material to pierce a Spartan's helmet,^[6] and the hull of a Lich.^[7]

The placement of the combat knife sheath varies depending on the combat uniform and individual loadout, and may be kept, for example, on the shoulder with the handle pointing downward, sideways on the lower back, or on the side of the boot.^[8] Some Spartan-IVs keep their knives sheathed in a wrist compartment.^[9]

There are a few different manufacturers of combat knives for the UNSC, including Watershed Division^[10] and Misriah Armory.^[1]^[11]^[12]^[13] In some cases, the Misriah logo was printed on the knife blade.^[1]

Usage

Some soldiers in service with the UNSC carry a combat knife of their own design or choice. Major Faison had a very large knife that he kept sheathed at his ankle, with the words "Bug-Hunter" engraved on the blade.^[14] Emile-A239 used a large kukri for his weapon of choice.^[15] Roland-B210, a member of the SPARTAN-III program's Headhunters division, also used a custom combat knife.^[16] Frederic-104 possesses particular skill with combat knives, and it can be interpreted that he has a liking for their use.^[17]^[18]

During the Battle of Trove, Sergeant John Forge's combat knife "Lucy" was used to seriously wound Arbiter Ripa 'Moramee, allowing Forge to kill 'Moramee with his own energy sword.

During the Battle of Kamchatka, Spartan Jameson Locke uses his combat knife to fight and kill Jul 'Mdama the leader of the reformed Covenant.^[19]

Variants

Large-scale manufacturing and broad leeway with usage means there are hundreds of variations available to UNSC personnel including kukris, ulus, billhooks, and push daggers.^[1]

When performing an assassination, any knives placed on armor will not be used. This can be seen in Theater: despite using a knife to assassinate your opponent, it still appears sheathed on your chest.
