Ven Zallow's lightsaber

Jedi Master Ven Zallow wielded a green-bladed lightsaber both in training and in combat, up until the moment of his death. Master Zallow's lightsaber was of greater heft and length than that of his Padawan, Aryn Leneer, who later acquired and kept the weapon after it was discovered in the rubble of the leveled Jedi Temple on Coruscant by Zallow's T7-O1 astromech droid. Both Master and apprentice—the latter of whom in the Jar'Kai style—used the lightsaber on different occasions against the Sith Lord Darth Malgus, the same man who killed Zallow while Coruscant itself was laid to waste.
