Ive done quite a few!!! you can do osage orange, african walnut, maple burl, derseert ironwwod, jigged bone, or smooth bone (honey, black, red, green, stag, imi-stag (from kovals very good imitation done in bone) ect. whatevers available). Its fairly easy though. What I do is pop off the old handles use them as a general template, and shape to fit. Polish with 400 grit, and then a little warm water with brasso and jewelers rouge mixed together with a buffing wheel on a dremel (and epoxy on with plastic weld epoxy, or 2 ton waterproof epoxy).
