The Grand Inquisitor's lightsaber

"Does yours do that?"

- Ezra Bridger to Kanan Jarrus

The Inquisitor's lightsaber was a unique variant of lightsaber wielded by the Jedi hunter known as the Inquisitor.

Specifications
The weapon featured a ringed emitter which could partially detach from the cylindrical handgrip in the center, allowing the twin blades to rotate rapidly without effort from the wielder.

The Inquisitor's personal weapon could also separate into two single-bladed lightsabers, and the handgrip could be removed entirely from the ring-shaped emitter, allowing the Force-imbued circlet of metal to be used as a throwing disc.

History
The Inquisitor wielded his lightsaber in several battles against Kanan Jarrus and Ezra Bridger. In a final battle against the Inquisitor, Jarrus split the Inquisitor's weapon in two, causing the pieces to fall down a shaft, followed shortly by the Inquisitor himself. It was also used to execute Imperial officers Cumberlayne Aresko and Myles Grint on Moff Tarkin's orders after their repeated incompetence in capturing the rebels.

Behind the scenes
The spinning lightsaber was an unused concept for the video game  The Force Unleashed.
