Light-whip

Lightwhip
A combination of a whip and a Lightsaber, the "lightwhip" has been created only three times: by the Sith Githany, Lady Lumiya and Obi-Wan Kenobi. It is a lightsaber crafted out of Kaiburr crystal and Mandalorian iron, but with the ability to flex and move like a leather whip. One was built by Obi-Wan Kenobi, who designed it from a whip he had seen a bounty hunter use. It was used by the Nautolan Jedi Kit Fisto and Obi-Wan during their mission on Ord Cestus.
