Shapton Pro (Kuromaku) sharpening stones are used for sharpening knives on KME and Hapstone knife sharpeners. Shapton Pro is a high-end series from Shapton made of aluminum oxide with the magnesia binder. The magnesia binder gives Shapton Pro excellent sharpening quality and performance, and high wear resistance.

Shapton Pro series stones are universal and can be used to sharpen knives of any steel including high carbon, vanadium, and chromium steels.

Shapton Pro stones are preliminarily lapped and do not require lapping after purchase.

Shapton Pro should be used with water as a lubricant. Do not soak Shapton Pro stones in water for more than a few seconds. Just splash, or use a water spray. Never store stones in water. Never dry near heat.

Advantages of aluminum blanks

  • If you accidentally drop the stone, it's less likely you break it;
  • Much longer life span for the stone after multiple flattening and lapping;
  • Easy identification due to laser engraving;
  • Reliable clamping for stones of imperfect shape.

Stones mounted on aluminum blanks are thicker than stock KME stones. We recommend using the thickness compensator if you use stones of different thickness.
