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.

Sharpening stones in sets (grain size format: Micron(UA) = ANSI(US) = FEPA(EU)

Set of 4 stones:
1. 100/80μ = 140/170 = D107, metal bond M2-01 - rough sharpening
