The Lightsaber is a product of an ancient technology, and the elegant weapon of the Jedi Knights. These power swords project blades of pure energy capable of cutting through most materials, except the blade of another Lightsaber.

The design seems simple from the outside: a handgrip, from 26 to 32 centimeters, with several switches ends in a mirror-like concave disk. Inside the handgrip, a single power cell produces a tremendous charge of energy which flows through a series of multifaceted jewels within. The jewels focus the energy into a tight beam that can be emitted from the disk above. The emitted beam arcs back from its positively charged continuous energy lens to a negatively charged high-energy flux aperture set in the disk.

The blade is usually a meter or so long. When activated, a lightsaber hums with power. Sabers with a single jewel have a fixed amplitude and blade length. Those with multiple jewels (usually no more than three) can alter their amplitude and change the length of the light blade. Though believed crude and somewhat useless in the eyes of a light Jedi master, this is accomplished by rotating an exterior control that varies the distance between the jewels.

The Lightsaber blade emits no heat, though it does fluoresce. While the beam is sharply tipped at the end, the saber's crystal is designed to create the illusion that the blade is the same width from source to end.

Considered archaic when compared to blasters and other modern weapons, Lightsabers are nonetheless impressive and power personal weapons that require extensive training to use effectively.

Tradition dictates that Lightsabers be constructed by their Jedi owners as part of the path towards true knighthood.
