High productivity of sharpening, second only to diamond, is provided by the use of abrasive grains of silicon carbide, which are distinguished by sharpness and brittleness. The high hardness of silicon carbide abrasives allows you to confidently process not only carbon steels, but also hard alloys, which is impossible on stones made of alumina powders. In addition to productivity, it is worth noting the extraordinary tactile sensations when sharpening the tool. The stones quickly slurry and produce a very pleasant sound.
PETROGRAD water stones are characterized by high performance and geometry as delivered.
In the characteristics of the water stone are indicated: the first letter - hardness (I, J - soft, K - medium); grain size according to the Japanese standard JIS R6001-1987 - 150 (80 microns), 360 (34 microns), 500 (24 microns), 1000 (12 microns), 2000 (6 microns) and the material is silicon carbide (C- green, B- the black). Comparison of FEPA, JIS and GOST standards:
