Rey Skywalker's lightsaber

Rey Skywalker's lightsaber was an at-least-single-bladed lightsaber, constructed by her notably from pieces of her quarterstaff sometime after the Battle of Exegol in 35 ABY.

Rey brought her lightsaber with her to the Lars homestead on Tatooine where she buried the lightsabers of Leia Organa and Anakin Skywalker, the latter of which also belonged to Anakin’s son, Luke.

This lightsaber used a rotating gear-like activation matrix rather than a standard button-and-switch.

Behind the scenes
Rey's lightsaber is the first instance of a yellow-bladed lightsaber in live-action media, though there are many instances of yellow bladed lightsabers in both the new canon and Legends lore, including Tosan's double-bladed lightsaber and the Lightsaber pikes of the Jedi Temple Guards.
