Previously known as the The Naniwa Super Stone, they 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. The Naniwa Advance Super Stones come in two varieties, the S1 and the S2. They are exactly the same except for thickness. The S2 Advance Super Stones are 20mm thick. The S1 Advance Super Stones are half that at 10mm thick. Both the S1 and S2 Advance Super Stones are 210mm long and 70mm wide (about 8-1/4" x 2-3/4"). Naniwa S2 Advance Super Stones are made with a resin bond. This resin bonding gives the Advance Super Stones their unique attributes: Splash and GoResin 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 FlatteningResin bonded Super Stones are harder wearing than many other water stones. S2 Super Stones won't dish or cup as quickly and will need less flattening less often. Higher Concentration of AbrasiveResin bonded Super Stones have a high concentration of abrasive particles which contributes to speedy sharpening.
