Skywalker lightsaber (Earth-2042)

"That lightsaber was Luke's. And his father's before him. And now it calls to you."

- Maz Kanata to Rey

The Skywalker lightsaber, also known at various times as Anakin, Luke, and Rey's lightsaber, or simply Rey's lightsaber in later years, was a blue-bladed lightsaber constructed by the Jedi Knight Anakin Skywalker during the fall of the Galactic Republic. Built as a replacement for Anakin's first lightsaber, the Skywalker lightsaber was carried by its creator throughout the Clone Wars and after Anakin turned against the Jedi Order by joining the Sith Lord Darth Sidious.
