These next generation stones were developed on the basis of our experience in sharpening business:
- solid support plate (thicker aluminum blank: 4 mm vs. competitors' 3 mm);
- appropriate bonds (selected, depending on grain size)
- combination of long life, delicate sharpening, and excellent performance of combined(metal-resin) bonds.
Concentration 100%.
Flat solid block on aluminum blank, grains are distributed evenly across the stone.
Material: CBN - cubic boron nitride. It has the best cost/productivity ratio for processing of steels, comparing to diamond and cheaper stones, they are similar in qualities to Japanese wet stones, but have ten times longer working life. CBN is a generic name, there are also other names of this material, depending on manufacturer: borazon, elbor.
