Rahm Kota's lightsaber

This green-bladed lightsaber was the chosen weapon of Jedi Master Rahm Kota, and was a heavy-duty model that saw frequent use. During the Dark Times, the Jedi General wielded this lightsaber during his personal insurrection against the Galactic Empire. In 2 BBY, Darth Vader dispatched Starkiller to kill Kota and bring him the lightsaber. Starkiller blinded Kota with his own weapon, and though the Jedi escaped, Starkiller turned it over to Darth Vader.

Darth Vader later gave the lightsaber to Starkiller to replace his original weapon after its loss. Masquerading as a Rebel, Starkiller wielded the lightsaber against various Imperial agents while assembling the Rebel Alliance and modified it to suit his own needs. After Starkiller was betrayed by Darth Vader, he wielded the lightsaber against his former master and bested him. Starkiller perished in a subsequent confrontation with Galactic Emperor Palpatine, and Vader destroyed the lightsaber.
