Mustafar bandit sword
From Wookieepedia, the Star Wars wiki.
The Mustafar bandit sword was a curved bladed weapon that was crafted from the metals mined on the lava world of Mustafar. The base of the sword was cut into jagged triangles allowing the wielder to better damage their enemy in close quarter fighting. The blade itself was not very lengthy which reduced its weight and allowed it to be balanced better during combat.
