Gatco Medium Diamond Sharpening Hone
Gatco's medium diamond maintains a keen edge on all of your knives and will handle minor repair work as well. While diamonds work faster, they scratch more aggressively so put in much deeper scratches leaving a more cloudy and toothy finish to your edge.
Like all Gatco handles it has their patent pending adjustable sliding guide rod and finger protection rails.
This stone is included in both of Gatco's diamond kits: the Gatco Edgemate Diamond Knife Sharpening System and the Gatco Edgemate Ultimate Diamond Knife Sharpening System
