Lightsaber

A lightsaber is a fictional weapon in the Star Wars universe, a "laser sword."

It consists of a polished metal hilt which projects a blade of light about 1.33 metres long.

Its distinct appearance was created using rotoscoping for the original Star Wars films, 

and digitally for the prequel trilogy.

The lightsaber first appeared in the original Star Wars film (1977) and every Star Wars 

movie to date (except The Star Wars Holiday Special) has featured at 
least one lightsaber duel. 

In 2008, a survey of approximately 2,000 film fans found it to be the most popular 
weapon in film history.
