Maul's lightsaber

Maul's lightsaber was a double-bladed lightsaber wielded by former Sith Lord Darth Maul, while he was hiding on the Sith planet of Malachor. He used it to fight the Inquisitors, and later the Jedi Rebels who came to Malachor seeking Sith knowledge.

The lightsaber produced two crimson-red blades, and the upper grip-guard resembled that of the Inquisitors' lightsabers, albeit broken and bent outward. It is unknown if Maul constructed the lightsaber himself, took it from a defeated Inquisitor, or found it on Malachor. He would hide the hilt by attaching a piece of wood to it, and pretending it was a walking stick, all the while masquarading as a feeble old man.
