Super Stone

Super Stone has been renamed twice within two years. So do not get confused with the names. Sharpening Stone is gone, and the Super Stone is back. 

Super Stone is a perfect overall sharpening stone. These stones are not as hard as Naniwa Professional Stone, but on the other hand, the finishing what you can achieve with these stones is fantastic.

Super Stone is Splash and Go whetstone, so a minimum amount of water is needed.
