Lansky Natural Black Hard Arkansas Sobha

This is a natural microcrystalline quartz and for its excellent grinding properties was used by Indians. According to some, the hard Arkansas is the highest quality stone made from Novaculite rock (1200-1400 grit).

Grinding with it is usually more time-consuming than with diamond grinding stones, but it almost does not wear out and remains in good condition.

Thanks to its very fine grain, you can achieve perfect sharpness of knife blades, chisels, and other cutting tools.
