A sharpening whetstone is a tool that creates a new, sharp edge on a kitchen knife by grinding away some of the metal from the blade. A sharpening whetstone is a flat, usually rectangular block made of natural or synthetic abrasive material, such as whetstone, oilstone, or diamond stone. Our whetstones are 100% corundum, a crystalline form of aluminium oxide that has a hardness of 9 on the Mohs scale Corundum whetstones are the ultimate choice for anyone who wants to have the sharpest and most refined knives in their kitchen.
