S2 Super Stone Series

The S2 Super Stone is a series of sharpening stones specially designed for achieving a perfect finish. These stones offer high polishing ability and maximum sharpness to your knife’s edge while remaining flat and intact over time. They provide a sharpening experience similar to that of soft natural stones and are suitable even for hard carbon steel blades.

Super Stone series stones require very little soaking time—often a simple spray of water is sufficient. The abrasive material used is aluminum oxide (corundum). The “S2” designation indicates a 2 cm thick stone.
