A Lightsaber is an energy weapon featured in the Star Wars universe. It 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. The Lightsaber’s energy blade can cut, burn and melt through most substances with little resistance. An active Lightsaber gives off a distinctive hum, which rises in pitch and volume as the blade is moved rapidly through the air. Bringing the blade into contact with another Lightsaber’s blade produces a loud crackle.
