Jedi Weapons

The lightsaber is the iconic symbol of the Jedi. Through the Force, it becomes an extension of the wielder; serving as both a powerful tool for defense and a devastating weapon against the dark side. Padawans, however, typically use electroblade training swords until they have proven themselves worthy. Only then can a Padawan make a pilgrimage to the Forge on Tython to construct a lightsaber in accordance with ancient Jedi traditions.

Lightsabers come in both single- and double-bladed forms, and their blades can be a variety of colors. Blue, green and yellow are the most common among the Jedi, though there are examples of other hues such as magenta and cyan. The color of a given lightsaber’s blade is largely determined by the crystals in the hilt that power the weapon. Different crystals confer varying properties on the weapon, allowing each lightsaber to be customized by its creator. (Codex Text - Star Wars the Old Republic)
