The Dual Kamas Prime are the first Prime dual swords to be introduced.
The Dual Kamas Prime was accidentally revealed in-game upon the release of Update 17.5, with its parts temporarily being made available as drops in the Orokin Void. This was later patched out in Hotfix 17.5.1.
Similar to the Dual Raza, the Dual Kamas Prime's blades are normally folded into the weapon when not in use, deploying only when attacking. If sufficient time has passed after the last attack, the Tenno will perform an animation where it flicks the weapons across its chest, stowing the blades away.
