A lightsaber with a blue blade once belonged to the Jedi Master known as Eno Cordova.
In the year 9 BBY, Cal Kestis, a Jedi Knight, acquired Cordova's lightsaber from Wayfinder's Tomb.
The initial appearance of Eno Cordova's lightsaber was in the 2019 Star Wars comic titled Jedi Fallen Order - Dark Temple 1, which was written by Matthew Rosenberg. Within the Star Wars Jedi: Fallen Order video game, players have the ability to gather Eno Cordova lightsaber parts during gameplay. This allows them to personalize Cal Kestis' lightsaber, in a similar fashion to the standard Jaro Tapal lightsaber components. It's worth noting that, in contrast to Tapal's lightsaber, the Eno Cordova lightsaber parts do not share a visual similarity with the weapon Cordova wielded in the Star Wars: Jedi Fallen Order - Dark Temple comic book mini-series.
