The double-bladed spinning lightsaber was a specially-designed lightsaber model used by the Inquisitorius, a group of Dark Side Adepts who enforced the will of the Galactic Empire. It was capable of both single and double blades, and was capable of spinning in a circular motion when both blades were emitted. Known wielders of this model included the Grand Inquisitor, the Fifth Brother, the Sixth Brother, the Seventh Sister and the Eighth Brother. As was custom with the Jedi and Sith, the lightsabers used by the Inquisitorius thus far have shown variation in the weapon’s design while maintaining core features.
The lightsaber’s overall design hardly made it any bigger than a single-emitter lightsaber, a stark contrast to the design of dual-blade weapons previously used by warriors such as Darth Maul. Another unique feature of this weapon is that the blade emitters would spin along tracks in the disc while the hilt would remain stationary in relation, allowing for more emphasis on the attack whilst maintaining a better degree of control over the weapon.
