Naniwa Dressing Stone 600 Grit (A-206)

The Naniwa Dressing Stone is an optional stone used for cleaning and refreshing the surface of Naniwa whetstones and other water stones. With this stone, it is possible to clean the surface of a water stone without without removing as much material as more aggressive flattening stone would. This is useful when your stone could use a cleaning, but doesn't yet need flattening.
