An energy cutlass, or painglass saber,[2] is a Covenant melee weapon primarily used by the Kig-Yar for light skirmishes in close-quarter situations. It is an energized cutlass forged using a modified energy projector with a Subanese crystal shard that has been chemically treated and sharpened into a blade.[2][3]

This bladed weapon is composed from a crystal shard from Suban and a complex arrangement of chemicals, plasma, and alloys. Just like the shattering of a fired Needler round, the blade of a painglass saber can be made to explode when it is embedded in soft flesh[1], making it a terrifying and cruel weapon. Before detonation, the blade will begin to pulse with a rosy red color.[4]


Referred to as chiss-teh by the Kig-Yar,[2] these crystal blades are utilized by Kig-Yar soldiers as well as pirates, as they make ideal weapons for boarding actions on hostile ships or in melee engagements in confined spaces.[5][1] Both Avery Junior Johnson and Nolan Byrne survived an encounter with these deadly arms upon making first contact with the Kig-Yar of Minor Transgression in 2525. Despite being pierced in his left thigh by a cutlass, Nolan Byrne managed to pull the blade out and even kill his alien attacker with its own weapon.[6]

The Unggoy also use them, as seen during the fighting on the Tiara during the First Battle of Harvest.[7] Energy cutlasses were used by several Kig-Yar during the Battle of Ariel in January 2552.[8]
