The set of narrow Boride stones is collected from various series and is intended for sharpening of knives from any steels. Narrow stones are very convenient for sharpening small knives and blades such as recurva. The set includes 5 stones with a grain size: 150; 220; 400; 600; 1200, which will be enough for all stages of sharpening, from peeling to the final grinding. And the smooth reduction of grain, from stone to stone, guarantees efficient sharpening with minimal time.
You can work both "dry" and with ordinary water (or a little soap). It is not recommended to use force and pressure during sharpening / finishing!
Does not require special care. Cleaned under running water with a soapy stiff brush (can be a toothbrush). Align after formation on silicon carbide.
Note: Boride stones can have the following defects: traces of a saw on a working surface, insignificant chips on corners and edges (the size no more than 1 mm).
