Darth Maul’s double-bladed lightsaber, also known as Maul’s saberstaff, was the first personal double-bladed lightsaber of Darth Maul, a Sith Lord who took part in the Invasion of Naboo and the Clone Wars. The Sith lightsaber was cut in half by Obi-Wan Kenobi during their duel on Naboo, and Maul continued to use the remaining half in battle until he temporarily lost it in his duel with his former master on Mandalore. He recovered the half after being freed from prison, and reformed it into a double-bladed hilt but lost it for good after a duel with Ahsoka Tano, subsequently replacing it with another double-bladed lightsaber that he would use up until his death.
The saberstaff consisted of two lightsabers fused together so the blades extend in a single line. Each blade could be ignited separately with blade modulation controls depending on the situation and the opponent being faced. Its design was based on ancient plans found deep within a Sith holocron owned by Darth Sidious.
In an interview with The Star Wars Show, Sam Witwer explained that the production of Solo: A Star Wars Story originally planned to reintroduce Maul’s double-bladed lightsaber during his scene with Qi’ra. Witwer, however, suggested using either the Darksaber or his Star Wars Rebels lightsaber and the latter remained.
During Star Wars Celebration Europe 2016 Ray Park revealed that originally Darth Maul’s double-bladed lightsaber was the same size as a regular single hilt lightsaber.
The new second half of the saber seen in Season 7 of The Clone Wars shares the appearance of concept art for Ventress’s lightsaber, that ultimately went unused due to the episodes in question turning into the novel Dark Disciple.
