So I decided to get me a Dark Sentinel, and throw a Kylo Ren spin on it. Here are a few thumbnails:
I started with weathering, rubbing sandpaper over the entire hilt and I'm pretty happy with it, though I may do more. I then wrapped the base in leather. The blade I covered in 2 tubes of clear silicone caulk, giving it that Kylo Ren appearance (if anyone's curious how to do that, I'd be happy to detail that here). I call this saber, "Knight of Ren"
And a video demo:
