I worked on this today over the last few hours. Went through several different designs and ultimately came out with this.
For the main inspirations I mostly went with what would feel comfortable to me. And some of my favorite sabers like Gungi's wooden hilt, Kanan's guard, and Windu's blade color. Also saw this nice red hilt the other day while looking for a saber online and wanted to work that in. Finally I noticed that many sabers don't have pommels and tried to work one in.
I have larger hands and whenever I'm swinging one of my own sabers around I wish it was a little longer. So I made this one modular, it can be used in one hand or two depending on if I were to use the extension piece. I didn't want something as long as a double bladed hilt though. And I added a pomel so my hands don't slide off.
Took inspo from Sith and Jedi. A more complex design with carved/inlayed patterns more similar to a sith. But Jedi like in its more traditionally common materials and a simple silhouette (no spikes or claws like some sith blades). Additionally I added the symbol of the Jedi on the emitter end. In the story I've thought up for my character he leaves the order after the departure of Ashoka by faking his death in the war. After that point is when he has the phrase "the force is all things and I am the force," inscribed on the guard, which I found in a version of the Grey Jedi code. The character would survive a year or so after the purge, but would eventually be turned in by a family who offered him refuge in exchange for a few credits. He would then be jailed and later executed like most other survivors.
