Chassantra's Lightsaber
Put this together at saberparts.com and then modelled it.
I wanted the handle to be relatively smooth and of even thickness. A lot of lightsaber designs out there have deep ridges, protrusions, varying thickness and so on that would make them very uncomfortable or even impossible to hold, at least with human hands. This one is likely not the most comfortable either, but it should at least be bearable.
The lightsaber belongs to a Sith named Chassantra, who, while being stranded and alone on an uncharted planet for 7 years, decided to renounce the ways of the Sith and walk a different path.

It's actually two lightsabers that can connect together at the base, allowing the wielder to switch between fighting with a lightsaber staff and dual-wielding lightsabers. This allows for great flexibility in combat.
Originally, the blades were crimson in color, due to the crystals being corrupted by the dark side. She tried to purge the crystals from the corruption, but did not manage to do so completely.
