S2 Super Stone Series

The S2 Super Stone is a series of sharpening stones specifically designed for perfect finishing. These stones offer a high polishing effect and maximum sharpness to your knife's blade. They remain flat and intact for a long time, while offering a sharpening experience similar to that of soft natural stones. They are ideal even for sharpening hard carbon steel.

In the Super Stone series, the stone requires much less time to absorb water—often, a simple spray is enough. Aluminum oxide (corundum) is the abrasive material used. The S2 designation indicates a stone thickness of 2 cm.
