Defender's Mettle (version 2)

All Lightsabers with the Vindican sound type have the same sound, including the Defender's Mettle (version 2). This isn't the official name, and this Lightsaber sound type may be labelled something like weaponmeleelightsaber04 in the background of the game.

I do not have a video of the Defender's Mettle (version 2), but you can watch a video of the Indomitable Vanquisher's Saberstaff weapon to hear the Vindican sound type, which is the same as the Defender's Mettle (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.
