Naniwa S2 Super Stone #220 (Made in Japan)

In short — abrasion. It’s an essential part of what industries do and must do exceptionally well.
Naniwa is a Japanese company with over 60 years of experience producing sharpening stones for both industrial and household use. They also manufacture diamond-based tools and other abrasive materials, continuously innovating to deliver precision and performance.

The Naniwa S2 Super Stone #220 is made using a resin-bonded structure that sets it apart from traditional water stones. The resin bond offers multiple advantages:

• Splash and Go: No soaking required. Simply splash a bit of water on the surface, and it’s ready for sharpening.

• Less Flattening Needed: Resin-bonded stones wear more slowly than standard water stones, maintaining a flatter surface for longer.

• High Abrasive Concentration: The high concentration of abrasive particles ensures fast, efficient sharpening.
