Unidentified Forerunner weapon

This unidentified weapon was a handheld energy weapon created and used by the Forerunners during the Forerunner-Flood War.

Description
It was a silver, claw-shaped device that generated what appeared to be a blade of some sort, capable of firing bolts of energy. When multiple weapons were used in conjunction, they could apparently combine their energy bolts to form a single large blade-like projectile that sliced through the air.

Trivia

 * The weapon's hilt is similar in design to a Constructor.
 * The means of activating the weapon is remarkably similar to that of the Covenant energy sword. It is possible that the weapon inspired the design of the energy sword.
