Luke Skywalker ' s green lightsaber Luke Skywalker ' s green lightsaber , also known as Luke Skywalker ' s lightsaber was a Jedi lightsaber constructed by Jedi Knight Luke Skywalker during the Galactic Civil War . It was notably wielded during the pivotal Battle of Endor . The green - bladed weapon was powered by a kyber crystal blade stabilizing ring surrounding the blade emitter . Skywalker constructed this lightsaber shortly after he lost his father ' s in the duel on Cloud City . Description . Built to replace his father ' s lightsaber , Luke Skywalker ' s own lightsaber contained a kyber crystal and emitted a green plasma blade . Its hilt was similar to that of Obi - Wan Kenobi ' s third lightsaber , as Skywalker modeled his weapon on his late Jedi Master ' s lightsaber , but simplified some of the design elements . History . Construction . During the Galactic Civil War , Luke Skywalker sought to construct a new weapon after he lost his first lightsaber in a duel on Bespin against Darth Vader , his father . Although his mentors , Obi - Wan Kenobi and Yoda , had told him only a little of the way a Jedi had to use the Force to build a lightsaber , Skywalker reached out with his mind and found the right pieces — some easily purchased , some much harder to acquire — during the time that followed the Battle of Hoth and his duel . Finally , during his return to his homeworld , Tatooine , to rescue his friend Han Solo from Jabba Desilijic Tiure , he was guided by the Force to Kenobi ' s hut . There , he found a few things Kenobi had left behind that were useful to him , including the missing parts he needed for his lightsaber ' s construction . After leaving Kenobi ' s hut , he knew he had at last collected everything he needed , and while his friends prepared for the upcoming rescue , Skywalker retreated into the solitude of a desert cave and puzzled over the pieces . He made use of the Force to put it all together and bring the crystal inside to life . When he was finished , he felt it truly was his lightsaber , almost an extension of himself . Usage . Rescue of Han Solo . Skywalker hid his lightsaber inside R2 - D2 ' s dome for the mission to rescue Captain Solo from Jabba the Hutt ' s palace . When he was about to be executed in the Great Pit of Carkoon , he gave the signal to R2 - D2 and the astromech droid returned the lightsaber to Skywalker . He then used it to cut Boba Fett ' s whipcord and EE - 3 carbine rifle in half . He also deflected blaster fire from Jabba ' s guards on the " Khetanna " , and killed some of them , including Klaatu . Battle of Endor . While on Endor , Skywalker used the weapon to protect himself from oncoming blaster fire from an Imperial scout trooper ' s 74 - Z speeder bike . As the scout neared , Skywalker sliced the front stabilizer s off , causing it and the driver to spin out of control and collide into a tree , killing the trooper and destroying the speeder bike . That same night , he turned himself in to the Endor Imperial garrison at their base and the lightsaber was confiscated by the Imperial officer , Commander Igar . The weapon was then given to his father , Darth Vader . As he examined the ignited weapon , Vader remarked that Skywalker ' s skills were complete with the lightsaber ' s construction . The weapon remained in his possession until Vader delivered it to his master , Emperor Palpatine , in the second Death Star ' s Throne Room . During the losing battle that the Alliance Fleet fought against the Imperial Navy , Palpatine tempted Skywalker to take his lightsaber and strike him down with it , so that he could give in to his anger and fall to the dark side . Eventually , in a moment of weakness , Skywalker took the weapon and attacked the Emperor , only for Vader to stop his strike and duel him . After almost killing his father , Skywalker realized what he was becoming , and he defiantly threw his lightsaber away and declared himself to be a Jedi . Following the Emperor ' s death at the hands of his father , Skywalker recovered his lightsaber . Stopping a Gorax . Sometime following the Battle of Endor , Skywalker and Organa helped the Ewok s Kneesaa and Wicket W . Warrick reset their traps to stop a Gorax . Skywalker used his lightsaber to slice through a log that the Gorax had thrown at him before Skywalker threw his lightsaber to Organa to use to cut a log . Pillio . Skywalker used the lightsaber sometime after the Battle of Endor time when investigating the planet Pillio . Skywalker used the lightsaber to defeat many stormtroopers and then help the Inferno Squad member Del Meeko in defeating native insects as they fought their way to the Emperor ' s Observatory . Skywalker and Meeko parted ways after Skywalker retrieved a compass . Vetine . Three months after the Battle of Endor , Skywalker would use the lightsaber during a mission to an Imperial research base on the planet Vetine in order to retrieve the last remaining fragment of a Force - sensitive tree . Skywalker gave his lightsaber to R2 - D2 for hiding as they entered the Imperial base . Once he revealed himself as a Jedi , R2 - D2 released his weapon and Skywalker used it to hold off the Imperial forces while Lieutenant Shara Bey recovered the tree fragments . Skywalker also cut through a cannon with his blade and eliminated several attacking stormtrooper s . New generation of Jedi . Years later , Skywalker would begin the training of a new generation of Jedi . Fearing the growth of the dark side of the Force within his Padawan and nephew , Ben Solo , Skywalker approached him as he lay asleep in bed where , overwhelmed by the darkness he sensed from Solo , he activated his lightsaber out of pure instinct . Immediately feeling a sense of shame in considering killing his nephew even only for an instant , Luke hesitated long enough for Solo to wake up . Upon seeing his Master standing above him with his lightsaber raised , Solo used his own lightsaber to defend himself , providing the catalyst that would ultimately lead to the destruction of Skywalker ' s Jedi Temple and the induction of Solo , who would become known as Kylo Ren , as master of the Knights of Ren under Supreme Leader Snoke . By 34 ABY , Skywalker was present in exile at the planet of Ahch - To , where he lived secluded in a hut without any connection to the Force . Behind the scenes . During Celebration V , Mark Hamill and George Lucas debuted a deleted scene from in which Luke activates his lightsaber for the first time . The clip was later included in the saga Blu - ray boxset . The scene was briefly alluded to in Tom Angleberger ' s canon junior novel adaptation of the film , " " .
