Naniwa Sharpening Stone 5000 S1-450

The S1 Super Stone series is the equivalent to the S2 Super Stone series. The only difference in the name is due to the smaller stone thickness of 10 mm. This stone series is an alternative at a lower price for grinding operations where only a small amount of material needs to be removed (suitable for polishing stones with fine grains).

Naniwa has changed the name and packaging of this series of grinding stones (first the Super Stone series only for Japan, then the Specialty series for Europe, and now Super Stone worldwide), but the stones themselves have remained unchanged.
