A lightsaber is a formidable weapon. It is a metal rod about a foot long. When a button is pressed, the energy inside is released, and a beam three to five feet long extends out of the emitter end of the rod. This beam, or "blade," consists of a white cord surrounded by a brightly-colored glow. This blade can deflect lasers and cut through any known substance, save the blade of another lightsaber. Many famous people wield lightsabers. They can fight with these.
Lightsabers were first built by WEEGEE! in an attempt to create a weapon that would be useful, yet compact. However, the first person to actually design lightsabers was Leonardo da Vinci in the eighteenth century A.D.
