The Naniwa Super Stone gained fame as a hard-wearing, splash-and-go stone that created an unbeatable polished edge on steel. Sharpeners fell in love with them for being so user friendly and such a good value.

At one point, the Super Stone line was divided in two with a thick and a thin version, and the name was changed to the Sharpening Stone for the thicker stone and the Specialty Sharpening Stone for the thinner. The renamed stones remained unbeatable quality, and they continued to gain in popularity due to their great value and excellent results. The original name had stuck though, and sharpeners continued to call them the Super Stone or sometimes the New Super Stone.

Now the name Super Stone is officially back. The Naniwa S2 Super Stone continues the tradition of quality. It is exactly the same stone as the one called the Naniwa Sharpening Stone, only the name and packaging has changed to reflect what discerning sharpeners have been calling it all along.

Resin Bonded

Naniwa Super Stones are made with a resin bond. This resin bonding gives the Super Stones their unique attributes:

• Splash and Go
  Resin bonded Super Stones don't require soaking in water prior to use. Splash some water on the top of the stone, and it is ready to go.
• Less Flattening
  Resin bonded Super Stones are harder wearing than many other water stones. Super Stones won't dish or cup as quickly and will need less flattening less often.
• Higher Concentration of Abrasive
  Resin bonded Super Stones have a high concentration of abrasive particles which contributes to speedy sharpening.

Available in 10 Grits
