Use this 220 grit sharpening stones to cut a uniform bevel, and for removing medium amounts of metal quickly. Unmounted aluminum oxide grit stones must be mounted to a "stone blank" (sold separately) to be utilized with the Edge Pro sharpening systems. Customers who go through many knife sharpener stones can remove their worn out stones from the existing stone blank and mount their unmounted stones to save money. EgePro suggests mounting the aluminum oxide sharpening stones using 3M's Super 77 adhesive spray.
Please note that unmounted stones are very thin and so very fragile. We wrap them carefully in bubble wrap so they'll make it to you in one piece, but you must exercise extreme care when unwrapping and mounting them. We are not responsible for broken or cracked stones after they reach you.
