In discussions and info surrounding The Force Awakens, it seems that a lot of the (now ancient) Jedi knowledge has been lost to time. Luke's Green lightsaber used a synthetic crystal, a practice usually resigned to Siths, and is said to be more cruder in design than the original ones. Likewise, Kylo Ren's lightsaber is said to be impure, primitive, and using a cracked crystal, resulting in a distorted blade with the need for side vents (the crossguards).

Of course, leading up to the end of the Clone Wars, most of the Jedi seem to have been wiped out, and one can assume that their weapons also followed suit. But do we know of any that have survived until the time of the Force Awakens? Other than Anakin/Luke/Rey's of course.

The only lightsabers I can remember from the original trilogy are:

• Anakin's original (blue)
• Taken by Obi-Wan towards the end of Episode III: The Clone Wars, and is kept by him until he passes it to Luke.
• Obi-Wan's (blue)
• Assuming he kept his original from the end of the Clone Wars.
• likely destroyed, either by Vader as a conclusion to their fight, or if it was left on the Death Star, exploded along with it.
• Vader's (red)
• I'm not entirely sure when this was crafted, but I assume it was during the conclusion of the Clone Wars or very soon after. At the very least, Anakin/Vader would've had original Jedi training on fashioning lightsabers so we can assume it's made to similar levels of quality.

Are there any other lightsabers that may have survived the Clone Wars and made it to the 'First Order' era?
