The lightsaber consists of a polished metal hilt which projects a blade of plasma about one meter long. The lightsaber is the signature weapon of the Jedi order and their Sith counterparts.
The lightsaber, is indeed an "elegant weapon", a powerful image combining the magic sword, light, fire, and energy. It is a laser; blocking another saber, it is light made solid, a remarkable concept. The sword, the active solar weapon of the hero-knight, has long been regarded as magical in itself, often having a name and a persona of its own in folklore and in such modern writers of traditionalist fiction as Tolkien, Bradley, and Moorcock.
