Silicon Carbide Stone Set 4" x 1"

Silicon Carbide Sharpening Stones are used for sharpening knives using KME and Hapstone sharpeners. The stones are made of silicon carbide and are designed for the hardest steels (up to 65 HRC). All stones are 6mm thick.

It is advisable to use silicon carbide stones for sharpening knives made of hard stainless steel or carbon steel, such as: ZDP-189, ZDP-247, S30V, S35VN, S90V, S110V, 154CM, D2, YXR7, Cowry, S290, S390, K294, K390, M390, Elmax, 154CPM, ATS-34, 440C, AUS-8, AUS-10, A2, BG-42. Using silicon carbide stones to sharpen knives made of soft steel is not recommended, as it will cause the stones to wear at the increased rate. However, coarse silicon carbide stones of 120 and 240 grit can be used as a universal stone due to their harder bonding.

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

Gritomatic Silicon Carbide Stones are preliminarily lapped and does not require lapping after purchase.

Gritomatic Silicon Carbide Stones are recommended to be used with water as a 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.
