Gatco Medium 400 Grit Diamond Sharpening Hone

The Gatco Medium 400 Grit Diamond Sharpening Hone is the middle step in a diamond progression for Gatco's clamp-guided kits. Gatco designed it to keep a keen edge on all knives once the coarse work is done. It is the hone most people reach for when touching up a knife that is dull but not damaged.

Diamond cuts faster than natural or ceramic stones and handles hard modern steels that can glaze a conventional stone. A diamond surface also stays flat through years of use, so it keeps giving an even bevel. The medium surface removes the scratches left by a coarse hone and gets the edge close to finished.

Gatco's guided kits clamp the knife in place and use a guide rod attached to the hone, so every stroke meets the edge at the same angle. You set the angle by placing the guide rod in a slot on the clamp, then work the hone along the edge in smooth strokes. Holding one angle from stroke to stroke is what produces a clean, consistent bevel instead of a rounded edge. Follow it with the fine diamond hone for a polished edge.
