Kao Cen Darach's lightsaber

The Jedi Master Kao Cen Darach owned a green-bladed lightsaber during the Battle of Korriban. He wielded his lightsaber when he fought the Sith Lord Vindican and manage to throw his lightsaber to save Satele from Darth Malgus's killing blow.

When Jace Malcom called for them to join him, Darach informed his apprentice to flee while he remained behind to hold off the Sith. As her master ran into the fray Shan threw her double-bladed lightsaber to him, which Darach used simultaneously with his own lightsaber to continue the battle, giving more time for her escape.

Despite being outnumbered, Darach proved to be an even match for Vindican and Malgus, even managing to mortally wound Vindican. Malgus seized the opportunity to force Vindican's lightsaber from hands and reciprocate his opponent's usage of three blades to re-engage the Jedi Master and managed to kill Darach.
