Description

Gritomatic Aluminum Oxide Sharpening Stones are used for sharpening knives using KME and Hapstone sharpeners. The stones are made of aluminum oxide and are designed for soft or medium steels (up to 59 HRC). All stones are 6 mm thick and mounted on high-quality aluminum blanks with laser engraving.

It is advisable to use aluminum oxide stones for sharpening knives made of soft stainless steel: 1095, 1080, 1070, 1050, 420, 440A, 440B, 3Cr13, 8Cr13MoV, 8Cr14MoV, 9Cr14MoV, AUS-4, AUS-6. Using aluminum oxide stones to sharpen knives made of hard steel is not recommended because of low performance.

The set includes 5 stones: 120, 240, 600, 1000 and 2500 grit (JIS).

Gritomatic Aluminum Oxide Stones are preliminary lapped and does not require lapping after purchase.

Gritomatic Aluminum Oxide Stones are recommended to be used with water as lubricant. Soak the stone for 1-2 minutes and splash water on the stone's surface to prevent drying.

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.
