Double-bladed lightsaber

The double-bladed lightsaber, also known as the saberstaff, was a lightsaber variant that featured a blade emitted from both ends. While lightsabers were utilized by users on both light and dark sides of the Force, only those practicing the dark side were known to use the saberstaff.

History
The Dathomirian Zabrak Sith Lord Darth Darth Maul wielded a red saberstaff he created himself, based on the ancient Zabrak weapon known as the Zhaboka. Savage Opress, Maul's brother, also wielded a red double-bladed lightsaber.

The Inquisitor, a Pau'an dark side adept tasked at identifying and hunting down Jedi following Order 66, fought using his own unique version of the weapon, his red double-bladed spinning lightsaber that could also be used as a regular single-bladed lightsaber.

Behind the scenes
The double-bladed spinning lightsaber first appeared in Star Wars Episode I: The Phantom Menace, wielded by Darth Maul, the fearsome villain featured in the film, seemingly slain by Obi-Wan Kenobi, but resurfacing in Star Wars: The Clone Wars. In The Clone Wars, he continue to wield this weapon as a regular single-bladed lightsaber, the other half having been cut off by Kenobi and lost.
