In the years before the Battle of Yavin, Ahsoka Tano used two white lightsabers as her personal weapons. The lightsabers, which were white in color and had somewhat curving hilts, replaced the lightsabers she previously used before leaving the Jedi Order during the Clone Wars and were wielded in the unorthodox reverse-grip of her preferred Shien style. One of these lightsabers was a shoto-style lightsaber, which emitted a shorter blade.
Ahsoka’s white lightsabers first appeared in the TV episode “Fire Across the Galaxy,” the season one finale for Star Wars Rebels. According to Dave Filoni, the lightsaber blades are white to reflect her non-affiliation with the Jedi or Sith.
