This article is about the Kig-Yar weapon. For other uses, see Knife.
The energy cutlass is a Covenant melee weapon, primarily used by the Kig-Yar for light skirmishes in close-quarter situations. Used by Kig-Yar soldiers and pirates alike, the energy cutlass is considered to be very useful during boarding actions on hostile ships or in melee engagements in confined spaces.
The weapon is composed of a complex arrangement of chemicals, plasma, alloys, and a shard of blamite. They are used primarily to dispatch enemies in close-quarters fights, especially when boarding an enemy ship. They are similar to the UNSC combat knife. These blades house a complex chemical mixture within them that causes the knife to explode into shards when embedded into a soft target, similar to a Type-33 Needler round. Before it explodes, the blade will begin to pulse with a rosy red color.
