Luke Skywalker's blue Lightsaber is a Weapon in the Star Wars universe. First wielded by Anakin Skywalker during The Clone Wars, the weapon eventually came into the hands of Luke, and evidence strongly suggests it subsequently came to Finn.
DescriptionLuke's lighsaber is an enclosed, reflective silver cylinder emitting a light-blue shaded blade of energy. Its design is reminiscent of Darth Vader's red lightsaber.
Over time it has been subtly tweaked and modified.
The saber was first created as a replacement for Anakin Skywalker's lightsaber destroyed just before the Battle of Geonosis. Anakin wielded the blade throughout The Clone Wars and the events of Revenge of the Sith, including the assassination of Count Dooku and his duel with Obi-Wan Kenobi. After maiming Skywalker on Mustafar, Obi-Wan took the blade, leaving Anakin for dead.
Obi Wan subsequently took the blade into exile on Tatooine. He wanted young Luke Skywalker to have the lightsaber when he was old enough, but Luke's Uncle Owen would not allow it.
After Skywalker encountered Kenobi near the Dune Sea, Obi-Wan presented Luke with the blade and explained that it had belonged to Luke's father. He offered Luke his first rudimentary training with the weapon aboard the Millennium Falcon during the passage to Alderaan.
Luke carried the lightsaber throughout the majority of the Galactic Civil War, gradually growing in skill and in the Force. The lightsaber was instrumental in his escape from the Wompa on Hoth.
When Luke faced Darth Vader in Cloud City on Bespin, he lost the saber along with his right hand to Vader's saber stroke. The saber plummeted down the principal pylon shaft on Cloud City and out of knowledge.
However, the saber re-emerged during Star Wars: The Force Awakens. Movie poster art shows Finn with Luke's lightsaver in hand.
Additionally, a brief clip released by Lucasfilm reveals Finn holding the saber in a combat pose.
However, these are misdirects. The lightsaber had come into the possession of Maz Kanata, the owner of a trading post on a forested planet. Rey heard the lightsaber "calling" to her when Han Solo took her to Maz to help her find the Resistance. When she touched it, she received a series of visions. Maz insisted that Rey should take it, and use it to find the now missing Luke. Rey refused and ran off. Maz then gave the lightsaber to Finn with the purpose of getting it to Rey.
Finn used to lightsaber to fight off the attacking First order, and took it with him to rescue Rey from Starkiller Base. There, he used it to fight Kylo Ren. Kylo disarmed Finn, severely wounding him. When he tried to grab the lightsaber, however, Rey picked it up instead, and used it to defeat Kylo. After escaping the base, she found Luke and presented the lightsaber to him once more.
