“This was the formal weapon of a Jedi Knight. Not as clumsy or random as a blaster. More skill than simple sight was required for its use. An elegant weapon. It was a symbol as well. Anyone can use a blaster or a fusioncutter—but to use a lightsaber well was a mark of someone a cut above the ordinary.” ― Obi-Wan Kenobi.
Designed as much for elegance in combat as for ceremony, the lightsaber, also referred to as the “laser sword” by those who were unfamiliar with it, was a distinctive weapon, the very image of which was inextricably bound with the mythos of the Jedi Order and their polar opposites, the Sith. The lightsaber also became synonymous with the Jedi Order’s values to uphold peace and justice throughout the galaxy. This perception endured, despite the many conflicts with lightsaber-wielding Sith and Dark Jedi.
“These weapons are not playthings. A lightsaber is a dangerous and destructive instrument, a powerful blade that can strike down an opponent—or a friend, if you’re not careful.”―Luke Skywalker to his students.
The weapon consisted of a blade of pure plasma emitted from the hilt and suspended in a force containment field. The field contained the immense heat of the plasma, protecting the wielder, and allowed the blade to keep its shape. The hilt was almost always self-fabricated by the wielder to match his or her specific needs, preferences and style. The hilt was also built similarly to his or her master’s lightsaber as a mark of respect. Due to the weightlessness of plasma and the strong gyroscopic effect generated by it, lightsabers required a great deal of strength and dexterity to wield, and it was extremely difficult—and dangerous—for the untrained to attempt using. However, in the hands of an expert of the Force, the lightsaber was a weapon to be greatly respected and feared. To wield a lightsaber was to demonstrate incredible skill and confidence, as well as masterful dexterity and attunement to the Force.
