Zez-Kai Ell's Double-Bladed Lightsaber (version 2)

All Lightsabers with the Attenuated sound type have the same sound, including the Zez-Kai Ell's Double-Bladed Lightsaber (version 2). This isn't the official name, and this Lightsaber sound type may be labelled something like weaponmeleelightsaber08 in the background of the game.

I do not have a video of the Zez-Kai Ell's Double-Bladed Lightsaber (version 2), but you can watch a video of the Interceptor's Lightblade (main hand) weapon to hear the Attenuated sound type, which is the same as the Zez-Kai Ell's Double-Bladed Lightsaber (version 2).

The Artifice crew skill trainer can teach players how to craft many crafted weapons sets as they level up in Artifice. However, these semi-retired crafted weapons sets are no longer available to be learned from the Artifice trainer from the launch of the game 1.0 - they were removed from the trainer in Update 4.0, and replaced with a more streamlined set of weapons schematics to be learned from the trainer. However, if you can find someone who learned the old schematics from the trainer pre-4.0, they can craft you these items, as the crafted items are Binds on Equip.
