SHAPTON K0705 water stone for sharpening 12000 grit A series of traditional water stones with a gradation of 120 to 30,000 grit. Each stone, in addition to individual marking with the product code, is also identifiable by a unique color. This allows you to quickly select a stone when sharpening knives. The stones are packed in special protective plastic boxes, which also act as a stand. Specially developed Splash&Go technology prevents excessive water absorption by the stone. It allows, during subsequent sharpening of knives, to spray the stone abundantly with water, without having to soak it again for a long time. Only when using the KUROMAKU stone for the first time, it should be soaked for about 6 minutes in water. The stones of the KUROMAKU series can be used both with water and with special sharpening oil. However, it should be remembered that if you choose oil as the medium that gives the stones moisture, you will not be able to go back to spraying the stones with water. Gradation: 12,000 grits Color: yellow Dimensions: 210x70x15mm Libra: Approx. 500g
