Luke's Green Lightsaber - What Happened To It?

The light saber that Mark Hamill's character Luke Skywalker uses in the first two Star Wars movies, A New Hope and The Empire Strikes Back, is actually his father's, which Obi-Wan Kenobi (played by Alec Guinness in the films) gave him.

In the prequel Star Wars movies, his father, Anakin Skywalker (Haden Christiansen), created the weapon. After Obi-Wan hands Luke the lightsaber, Luke uses it until Darth Vader takes it away from him in the famous Cloud City scene at the end of The Empire Strikes Back.

When Luke resurfaces in Return of the Jedi, he is carrying a weapon that reflects his own Jedi qualities and was created by his hand and abilities. This saber is among the greatest in the series, and it's brilliant green. Despite the blade's clear color difference, the handle is modeled after Obi-Wan Kenobi's saber.

Luke now has a green one, correct? Well, it's not quite that simple.

In The Force Awakens, we witness Maz Kanata (Lupita Nyong'o) give Luke's blue lightsaber to Rey (Daisy Ridley), a Jedi pupil. So it's not lost? Then, Luke is eventually discovered hidden on a secluded island on the planet Auch-To, without his second saber, the green lightsaber. That one went where?

Does a thorough analysis of the stories offer a solution, or is this only a continuity problem on the filmmakers' part?

It becomes evident that Luke chose the green saber as his primary weapon. He built it himself, and after he saves Han Solo, he uses it on Tatooine to murder Jabba desilijic Ture's bodyguards. Based on the scene in Return of the Jedi where Luke throws the green saber aside and surrenders to the remaining kindness and goodness of his father, Anakin, who was still wearing the Darth Vader costume and persona at the time, it was long believed that Luke lost the saber when the second Death Star exploded.

With the publication of The Last Jedi in 2017, which features a flashback to Luke's Jedi school, that presumption was disproved. Luke faces his nephew Kylo Ren (played by Adam Driver), who was once Ben Solo (the son of Han Solo and Princess/General Leia), in the flashback sequences. Prior to the events of The Force Awakens, Luke was instructing a new generation of Jedi warriors, demonstrating his green lightsaber. Thus, even after Return of the Jedi ended, Luke still possessed the green saber.

The reason? Fans have never received any, which may indicate that it was an easy error.

Luke never discloses the location of the green lightsaber he created in the sequels. We don't know if he threw it away, lost it, or gave it to someone else as a sign of the disavowal of his attempts to uphold and spread the Jedi way. Why doesn't he use it if he still has it?

Some ideas have been put forth.

Initially, when the new Jedi Order collapsed, he may have lost it during the conflict with Kylo Ren. Because he felt unworthy of becoming a Jedi, let alone training more of them, Luke may have destroyed his weapon following those incidents. It could have been tossed into the sea when Auch-To sank the X-Wing, sinking it in the waters nearby. A lightsabre might have been swept away, but the X-Wing would probably remain in position, like a shipwreck.
