I would like to reshape the handle on one of my knives. I won't need to remove too much material to get what I want. The handle has the overall shape I want, I will just be making it rounded instead of multi-faceted as it is now. I plan to do it by hand, unless it becomes to arduous. My plan was to work slowly using increasingly fine grit sandpaper as I progress. Does this sound reasonable? I have access to a belt sander as well, but I am a little concerned with running amuck and taking off too much material.
