Blue Belgian Whetstone 5000-6000

Blue Belgian Whetstone 5000-6000.
The stone represents composition of shale and sandstone with impregnations of garnet crystals. These protruding crystals provide the abrasive effect. Bluish-purple colour of the stone comes from the presence of iron oxide. The concentration of garnet grains in Blue Belgian Whetstone is 25-30 % of the total volume of the stone (grain size from 10 to 25 microns). Blue Belgian Whetstone has high hardness and works more aggressively than Coticule Whetstone. And at the same time works fine and quickly.
The stone is suitable for TSPROF K03 and Blitz knife sharpeners.
