For Micarta, I usually go to 220 on the belt sander, then drop to 120, 180, 220, 320 and then 400 by hand, then go over to my lathe with a Sisal buff mounted with some white buffing compound and polish it up. I do sometimes use the Tru Oil on the handles. I use a couple of drops and rub it into the handle and wipe off the excess. It keeps the handle from turning dirty looking and seals the pores a bit more than the buffing does.
