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 6 mm 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 an at increased rate. However, coarse silicon carbide stones of 120 and 220 grit can be used as a universal stone due to their harder bonding.
Gritomatic synthetic stones made of silicon carbide and aluminum oxide can be labeled in either FEPA-F or JIS grit scale. To make grit uniform and customer-friendly, we have started transition to the japanese (JIS) grit scale for all Gritomatic waterstones. Old naming: F 120, F 220, F 400, F 600, F 1000. New naming: 120, 240, 600, 1000, 2500.
Gritomatic Silicon Carbide Stones are preliminary lapped and does not require lapping after purchase.
Gritomatic Silicon Carbide 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.
