Depiction

Lightsabers were present in the earliest drafts as mundane laser weapons that were used alongside laser guns.[5][6] The introduction of the Force in a later revision made the Jedi and the Sith supernaturally skilled, eventually the only swordsmen. The lightsaber became the Force-user's tool, described in-universe by Obi Wan Kenobi as "not as clumsy or random as a blaster. An elegant weapon, from a more civilized age."
