Use our 1000 grit aluminum oxide water stones for achieving an ultra-fine edge on your recurve blade. Unmounted 1000 grit sharpening stones must be mounted to a “½” stone blank” (sold separately) to be utilized with the Edge Pro sharpening systems. Customers who go through many Edge Pro sharpener stones can remove their worn out stones from the existing stone blank and mount their un-mounted stones themselves saving 50% off the mounted stone price. We suggest mounting the aluminum oxide sharpening stones using 3M’s Super 77 adhesive spray.
