It is called a Darksaber.. Keyword Saber. Lightsaber keyword Saber. Dark vs Light. Yes it is a Jedi weapon it is a darksaber.. Did I repeat it enough for you to comprehend.. Thank You and you have yourself a great day.

Maybe you should do some research.. Pre Vizsla wielded a black bladed darksaber in the clone wars.. How are people going to talk about how they know so much about star wars and than be completely off base.. Fail.
