Lightsaber

A lightsaber (or lightsabre, see spelling differences) is a weapon made popular in the Star Wars universe. A “laser sword,” it consists of a polished metal hilt which projects a blade of plasma about 4 feet or 1.33 meters long. The Lightsaber is the signature weapon of the Jedi order and their Sith counterparts, both of whom can use them for close combat, or to deflect blaster bolts.
