After a night of sitting, un-clamp it and get a feel for your handle. you may just want to round it out and leave it as is! For mine, I took the handle to the belt sander and made myself some finger slots, then clamped the blade into the vice and rounded the edges with a rasp. The sky is the limit here! After you have obtained your final look, you can sand it down so its smooth with 180 grit.
