The Grand Inquisitor's lightsaber

"Does yours do that?"

- Ezra Bridger to Kanan Jarrus

The Grand Inquisitor's lightsaber was the personal double-bladed spinning lightsaber of the Jedi hunter known as the Grand Inquisitor, similar to those wielded by the other Imperial Inquisitors.

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. For a Jedi hunter like the Inquisitor, this function likely served as a way to intimidate, or frighten opponents, as well as deflect any form of direct attack. On some occasion this function is known to catch opponents off balance. However, this was also the weapon's primary weakness, as a lightsaber-wielding opponent could simply permanently separate the emitter itself and sever the weapon in half, as was demonstrated by Lord Vader during his first duel with the Inquisitor and Kanan Jarrus during his final duel with the Inquisitor aboard the Sovereign. This is due to the hilt consisting of non-lightsaber resistant alloy or metal.

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 Grand Inquistor wielded his lightsaber against Emperor Palpatine's new apprentice, the Sith Lord Darth Vader. During their fight, Lord Vader was able to damage the Inquisitor's lightsaber.

The Grand Inquisitor wielded his lightsaber in several battles against Kanan Jarrus and Ezra Bridger. It was also used to execute Imperial officers Cumberlayne Aresko and Myles Grint both at once on Moff Tarkin's orders, after their repeated incompetence in capturing the rebels. In a final battle against the Inquisitor, after his rescue, Jarrus split the Inquisitor's weapon in two, causing the pieces to fall down a shaft. The two halves were then destroyed in an explosion when they fell into the Sovereign engines, followed shortly by the Inquisitor himself.

Behind the scenes
The spinning lightsaber was an unused concept for the video game  The Force Unleashed. Furthermore, a similar saber, attributed to General Grievous, was previously made into a toy by Hasbro as part of The Clone Wars toy line.
