Anakin Skywalker

Anakin Skywalker, who later becomes Darth Vader, constructed the lightsaber himself as a young Jedi Padawan, using a rare crystal called a Kyber crystal that he obtained on the planet Ilum.

The lightsaber's hilt was made from parts that Anakin salvaged from an old podracer engine, giving it a distinctive and slightly rough appearance. The blue blade of the lightsaber is also notable because it represents Anakin's original allegiance to the Jedi Order before he ultimately falls to the dark side and becomes a Sith Lord.

Following his turn to the dark side, Anakin still used his Jedi weapon, which later became the weapon of Darth Vader. Tionne Solusar speculated that he kept using the blue-bladed weapon to prevent his victims from becoming suspicious of his recent conversion.

Anakin Skywalker constructed his first lightsaber, which had a blue blade, during his Initiate's Gathering trial in the Crystal Caves of Ilum when he was thirteen years old. He assembled the hilt while in an entranced state, using parts he had previously built. This lightsaber was the first one ever created by Anakin Skywalker.

Following their fateful duel on Mustafar, Obi-Wan Kenobi retrieved Anakin's lightsaber and kept it in his possession on Tatooine for almost 20 years. Eventually, he passed it on to Luke Skywalker, who unfortunately lost it when his hand was severed by Darth Vader during their confrontation in Cloud City.

Darth Vader pursued Jedi Master Kirak Infil'a to Al'doleem's river moon and engaged him in a confrontation. After defeating the Jedi Master, Vader claimed his distinctive curved-hilt lightsaber. Later, on Mustafar, Vader corrupted the saber's crystal, changing its color from green to red.
