Checkering tools from series N3, have two sides: the right side is smooth, used as a guide, the left - with teeth. All the cutters are made of steel, underwent a process of hardening and processing, for long and reliable work.

Water stone. 2000 grit. Size 200*70*20mm. Abrasive grain - silicon carbide. Bundle - ceramics. Hardness I ensures minimal wear of the stone during operation. When sharpening does not overheat the steel. Does not require the use of oil. Soak in water for 2-10 minutes before use. Used for sharpening and setting bevels.

High sharpening performance, second only to diamond, is ensured by the use of silicon carbide abrasive grains, which are notable for their sharpness and brittleness. The high hardness of carbide-silicon grinding materials allows you to confidently process not only carbon steels, but also hard alloys, which is impossible on stones made of electro-alumina powders. In addition to performance, it is worth noting the extraordinary tactile sensations when sharpening a tool. Stones quickly give a slurry and produce a very pleasant sound.

Water stones PETROGRAD are distinguished by high performance and geometry in a state of delivery.
In the characteristic of a water stone are specified: the first letter - hardness (I, J - soft, K - average); Japanese grain size according to JIS R6001-1987 is 150 (80 microns), 360 (34 microns), 500 (24 microns), 1000 (12 microns), 2000 (6 microns) and C is silicon carbide.
