A lightsaber is an amazing and versatile eweapon that is used by a Jedi.In comparison to these, blasters are pathetic.To carry a lightsaber is an example of incredible skill. The blade of a lightsabre can cut through almost anything, except the blade of another one.
They are the best weapons in the universe basically.

A Jedi Knights weapon of choice the Light Saber is less clumbsy than a blaster, and is more of a symbol of honor, and wisdom than a weapon. A Light Saber\'s color depends upon the type of crystal put into the hilt during its building, and the crystal really depends on the Jedi\'s personality, and their particular alliance. Jedi\'s (the good guys) usually have stoic colors or softer colors which give off a prescence of being good such as blue, green, yellow, purple, etc. The Sith (the bad guys) more or less stick with one dominant color that gives off a presence of evil, red, dark red, crimson, take your pick. In closing Light Sabers kick ass, and I wish the government would go public with their mass production of the powerful sabers....Oh come on, we all know that its true...

The best single weapon in the history of cinema. Utilised in the star wars films, lightsabers (or sabres - if you're UK) consist of a handle (like a flashlight tube) and emit a brilliant lazerbeam like shaft of colour. The traditional colours of the blade are green or blue for Jedi (goodies) or red for the baddies - the Sith. The exceptions are Mace Windu played by Samuel L Jackson who has a purple one because Jackson wanted to look cooler than everyone else. And General Grevious who weilded stolen Jedi sabres. Also in Revenge of the Sith Darth Vader still uses his Jedi blue sabre - though he switches to red in the time between episodes III & IV.

Lightsabres are able to cut through anything, apart from the blade of another sabre. Because of this it's an ideal 1v1 weapon for close combat. These duels are the highlights of the Star Wars films. Here, in order are the sabrefights;

A terrible weapon Lockheed Martin is developing in case of war against France. Unfortunately the huge amount of light sabers produced might drive the United States to the third Bush administration.
