Skywalker lightsaber

"What is it?" "It's your father's lightsaber. This is the weapon of a Jedi Knight. Not as clumsy or random as a blaster. An elegant weapon, for a more civilized age."

- Luke Skywalker and Obi-Wan Kenobi

During the Clone Wars, Jedi Knight Anakin Skywalker constructed a lightsaber to replace the one he lost shortly before the Battle of Geonosis.

Skywalker used this lightsaber throughout the war, and he briefly continued to use it after falling to the dark side of the Force and becoming Darth Vader, a Dark Lord of the Sith. He lost the lightsaber during a lightsaber duel against Obi-Wan Kenobi, who kept it in his possession while in exile on Tatooine.

During the Galactic Civil War, Kenobi later passed it on to Vader's son, Luke Skywalker and he used it for three years before losing it in duel against the Dark Lord.

Description
The lightsaber of the Jedi Knight Anakin Skywalker contained kyber crystals that generated a blue plasma blade.

Carried by Anakin Skywalker
Skywalker used this weapon to duel and defeat the Sith Lord Count Dooku, also known as Darth Tyranus during the Battle of Coruscant. He later lost the weapon while effecting the rescue of Supreme Chancellor Palpatine and it was retrieved by one of General Grievous's IG-100 Magnaguards. The weapon was then given by the Magnaguard to Grievous, who briefly wielded it, but Obi-Wan Kenobi used a trick of the Force to recover it and restore it to Anakin.

Skywalker later used the weapon to slaughter many of his fellow Jedi during his Attack on the Jedi Temple. After this, he slaughtered the entire leadership of the Separatist Council on his Mission to Mustafar. He then lost the weapon in his duel with Kenobi.

Obtaining the weapon
"Your father wanted you to have this when you were old enough, but your uncle wouldn't allow it. He feared you might follow old Obi-Wan on some damn fool idealistic crusade like your father did."

- Obi-Wan Kenobi to Luke Skywalker

Anakin's lightsaber remained in the possession of Kenobi's for nineteen years, until he was given an opportunity to give the weapon to Luke Skywalker, Anakin's son, after rescuing Luke from a Tusken Raider attack. At his hut, Kenobi presented Skywalker with his father's lightsaber stating that his father wanted him to have it when Skywalker was old enough but his uncle Owen Lars wouldn't allow it as he thought Skywalker would follow in his father's footsteps and join Kenobi on some "damn fool idealistic crusade". Following the death of aunt and uncle, Skywalker became Kenobi's apprentice and started to learn the ways of the Jedi. During his voyage to Alderaan, Skywalker began training with the weapon onboard the Millennium Falcon where he used the Jedi form of Shien, to deflect blaster blots from a training remote.

Usage on Cymoon 1
"You hold that weapon like an untrained child. You have no right to it."

- Darth Vader to Luke Skywalker

Following Kenobi's untimely demise at the hands of Darth Vader, Skywalker began to teach himself how to wield his father's weapon. On the moon of Cymoon 1, Skywalker participated in an assault on the moon to infiltrate and destroy the weapons factory Alpha. After the Force guided Skywalker to a cage filled with Imperial slaves, where he was confronted by a guard. Skywalker first attempted to use a Jedi mind trick to ward the guard off, but when that failed, Skywalker ignited his lightsaber and sliced the guard's hand off, allowing Skywalker to break the slaves out of their cage and lead them to the other Rebels. . When Skywalker found out that Darth Vader had arrived on the moon, Skywalker searched for him in the facility, as he still believed that Vader was the man who killed his father. As Skywalker approached the Dark Lord, he had his lightsaber drawn and activated as he came face to face with his father's so-called killer (and Obi-Wan Kenobi's).

Usage on Hoth
When Skywalker was captured by a wampa, a creature native to the ice planet of Hoth, he found himself hanging upside down from the ceiling of a cave that the wampa resided in. Seeing his weapon on the floor, he used the Force to call the weapon to him, cutting himself free and slicing off one of the wampa's arm allowing him to escape.

When Han Solo found Skywalker nearly frozen to death, he used the lightsaber to cut open his dead tauntaun and keep Skywalker warm while he put up shelter.

During the Battle of Hoth, Skywalker using the combined ability of a grappling device and his lightsaber to cut open a hatch on the bottom of an Imperial AT-AT walker prior to throwing in an explosive to destroy the enemy vehicle.

Usage on Dagobah
During his training with Jedi Master Yoda on the planet Dagobah, Skywalker entered a cave that was strong with the dark side as a test given by Yoda. In the hollow, Skywalker had a vision in which he faced Darth Vader, the Dark Lord of the Sith. As Skywalker used his lightsaber to strike down Vader with a high lightsaber blow, the illusory Sith Lord's helmeted head rolled on the floor, and the face shield cracked open to reveal the young Jedi's own countenance behind the mask.

Duel against Darth Vader
Following his duel in the dark side cave, Skywalker received a force vision of his friends being in pain on the Cloud City on Bespin. There, he faced Darth Vader in a lightsaber duel, where Skywalker demonstrated his new found skills with the weapon, that impressed even the former wielder. During the battle, due to Skywalker's fatigue, Vader sliced Skywalker's hand off that was holding his lightsaber and fell, along with the lightsaber it carried, into the depths of Cloud City. Following losing this lightsaber to Vader, Skywalker built himself a new lightsaber to replace the one he lost.
