This 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.

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.
