Prior to the first battle of the Clone Wars , Count Dooku — a former Jedi Master who joined the Sith as Darth Tyranus , apprentice of the Sith Lord Darth Sidious — handcrafted a curved - hilt lightsaber which he used to defeat the Jedi Knight Obi - Wan Kenobi and Padawan Anakin Skywalker on the planet Geonosis . However , he was ultimately bested by his former Jedi mentor , Grand Master Yoda of the Jedi Order , and subsequently retreated from the battle . Over the course of the galaxy - wide conflict between the Galactic Republic and the Confederacy of Independent Systems , Tyranus dueled with Kenobi and Skywalker on several occasions , as well as his prospective apprentices Ventress and Savage Opress . In his final bout which took place during the Battle of Coruscant , Tyranus was disarmed and beheaded by his nemesis Skywalker , who used his own lightsaber and the Count ' s weapon to carry out the execution . Asajj Ventress . Though initially trained as a Jedi Padawan , Asajj Ventress switched her green - bladed lightsaber for a pair of red - bladed curved - hilt lightsabers during her years as Darth Tyranus ' s apprentice . Throughout her time in service to the Sith cause , Ventress utilized her lightsabers in several capacities — as her master ' s emissary and assassin , as well as a military commander of the Separatist Droid Army . She fought a number of Jedi on several occasions with varying degrees of success , such as Kenobi , Skywalker , Luminara Unduli , and Ahsoka Tano . Ventress retained her Sith lightsabers after Tyranus discarded her on the orders of his master , Darth Sidious , and continued to use them as a Nightsister before pursuing a career as a bounty hunter . Both lightsabers were lost when the fallen Jedi Barriss Offee ambushed Ventress in the Coruscant underworld and took possession of her weapons , consequently forcing the bounty hunter to acquire a replacement . Offee was later forced to use Ventress ' s lightsabers when Skywalker confronted her in the Jedi Temple , and thereby revealed herself as the culprit responsible for framing Tano .
