Description

The extremely high density of abrasive grains in this stone series enables rapid material removal. The hard magnesium bond also keeps the stone flat for a very long time - making it ideal for kitchen knives, razors and all low-alloy carbon steels with high hardness (White and Blue Paper Steel).

Thanks to this bond, the stone reacts more sensitively to prolonged exposure to water - therefore only soak for max. 5 minutes before use!

Naniwa has changed the name and the packaging of this sharpening stone series (formerly Professional Stone Series). The sharpening stone itself has not been changed.
