Double-bladed lightsaber/Legends

The double-bladed lightsaber, also known as  Sith lightsaber or  saberstaff, was a specialised form of lightsaber. Utilizing the same technology as a standard lightsaber, the double-bladed Lightsaber was designed with two blades attached to each other. This made it twice as powerful with "more kills per swing" as some put it. It could activate each blade independently of the other and had a slightly longer grip than a normal lightsaber had.

During the Jedi Civil War, the double-bladed lightsaber was a popular weapon for the Sith followers of Darth Revan and Malak. Even the Jedi Knights, and some Jedi Masters, used the weapon during those dark times, but the Jedi Council traditionally frowned on use of the blade, believing a traditional lightsaber was enough, and considering the double-bladed saber little more than a weapon designed to kill, while the Jedi developed the lightsaber to defend.
