Sith sword

Sith swords were weapons used by the Sith during the Sith Empire. Developed by the Ancient Sith, it was adopted by the Dark Jedi when they arrived on Korriban. Sith swords were altered by Sith Alchemy to be harder and sharper. They were never dulled, could block blaster fire, and even resist Lightsabers.

After the fall of the Sith Empire, the Sith abandoned the Swords in favor or lightsabers.
