Described to Luke Skywalker by Obi-Wan as an elegant weapon for a more civilized age, the lightsaber has become one of the most recognizable icons from the saga. The lightsaber fulfilled an important symbolic role in A New Hope. When Luke gets his father’s lightsaber, the young farm boy receives his talisman, a powerful symbol of his heritage. Similar moments in mythology occur when Arthur Pendragon receives the sword Excalibur or when the Norse hero Sigurd gets the sword Gram which he will use to kill the dragon Fafnir. In this feature we’ll have a look at the lightsabers of four Jedi who played a crucial part during the events of the Star Wars movies.

Qui-Gon Jinn’s lightsaber
The lightsaber used by Qui-Gon Jinn during the Invasion of Naboo wasn’t as ornate as the weapon used by his former Master, Dooku. Qui-Gon built his saber so it could be used to handle both classic and other fighting techniques. The metal hilt was 28.50 centimeters long and 3.80 centimeters wide. Qui-Gon used an Adegan crystal for his green saber. This lightsaber’s special feature were many micro-power cells, inserted in the ridged handgrip. Those cells gave Qui-Gon more control over the power levels of the saber. The weapon had a red activator button and a charging port at the side.

 After Qui-Gon had been mortally wounded by Darth Maul on Naboo, Obi-Wan Kenobi grabbed the lightsaber with the Force and used the weapon to slice the Zabrak in half. Obi-Wan temporarily gave Qui-Gon’s weapon to Anakin Skywalker after he had built a new lightsaber. Eventually the lightsaber ended up in a memorial in the Jedi Temple.
