The AS V6 Dark Lord is the final version of Anakin Skywalkers lightsaber, as it transitioned over the years from the Graflex AS V1 to the final Darth Vader version AS V6. This is a variant version for Darth Vader's lightsaber, a Sith Lord who served as Darth Sidious' last apprentice and supreme military commander of the Galactic Empire.  He built the weapon after he lost his previous saber during a skirmish on Cabarria.  The lightsaber was later used to kill Obi-Wan Kenobi.  
 
The lightsaber was equipped with a dual-phase function, allowing the blade's length to be manually controlled and altered in combat.  The weapon featured a black-ridged handgrip, black power cell chamber, beveled emitter shroud, two dual-phase focusing crystals, high-output diatium power cell, and customary power and length adjustment knobs.  Darth Vader was constantly fine-tuning and upgrading his lightsaber for maximum blade power and stability.
 
This model features an exposed kyber crystal!  A kyber crystal, simply known as a kyber, also called a lightsaber crystal, the living crystal, and known in ancient times as a kaiburr crystal, was a rare, Force-attuned crystal that grew in nature and was found on scattered planets across the galaxy.  They were used by the Jedi and the Sith in the construction of their lightsabers.  As part of Jedi training, younglings were sent to the Crystal Cave of the ice planet of Ilum to mine crystals in order to construct their own lightsabers.

Hilt Length: 11.42 inches (29 cm)
