lightsaber

Fictional weapon

A lightsaber is a fictional energy sword featured in the Star Wars franchise. A typical lightsaber is depicted as a luminescent blade of magnetically contained plasma about 3 feet (0.91 m) in length emitted from a metal hilt around 10.5 inches (27 cm) in length. First introduced in the original Star Wars film, it has since appeared in most Star Wars films, with at least one lightsaber duel occurring in each installment of the "Skywalker saga". The lightsaber's distinct appearance was created using rotoscoping for the original films, and with digital effects for the prequel and sequel trilogies.
