Dan..., as has been suggested, pumice stone with paraffin oil or mineral oil works very well in cutting back the shine. Use an old tooth brush and scrub the stock with the pumice stone and oil mixture. Do a small section and go slow, until you get the desired result, then do the same for the rest of the stock. Wipe off the mess with a clean cloth, and you’ll get a very nice, warm looking finish. Best,
