Venev CBN 150x24x11 B2-01 and OSB 100%

Metallic CBN Sharpening Stones: are used for sharpening knives using Hapstone sharpeners. CBN (Cubic Boron Nitride) is the second-hardest material after diamond.
CBN's qualities include its high levels of high hardness, strength, abrasion resistance, and thermal and chemical resistance. These characteristics exceed the values of synthetic diamonds and conventional abrasives such as silicon carbide and aluminum oxide. In particular, CBN's high thermal stability and chemical resistance make it suitable for sharpening in conditions where synthetic diamonds are not normally employed.
CBN offers excellent performance in sharpening knives of any steel. Due to its high resistance, CBN can be used dry without lubricant. This makes CBN the cleanest of the available sharpening stones.
Metallic CBN stones utilize copper-tin alloy bonding for high endurance and low wearing rate. Metallic CBN Stones consist of a 3 mm thick CBN-bearing metal plate

Side 200/160, 160/125, 100/80, and 50/40 are made on an organic bond B2-01. Organic ligament consists of phenol-formaldehyde resins and various compositions based on them. These, during hot pressing, are Bakelized into a solid and sufficiently strong substance that holds the cutting grains in the active layer of the tool. Moreover, such a bundle will be adequately strong and vicious, but not rigid enough. To give it rigidity, abrasive grinding powders, such as boron carbide, are added.

The 20/14, 7/5, 3/2, and 1/0 side is made on an improved organic OSB bond. This modernized bond is based not on a grinding powder but on a micro-powder of the ACM brand, made of synthetic diamonds of standard abrasive capacity. The difference between the OSB bond and others is that it does not use boron carbide. In addition, the abrasive layer on it is not sintered but is glued to the body of the metal plate. The absence of unnecessary inclusions of other abrasives makes it possible to do softer and finer work. OSB bond is ideal for hard steels at small angles.

The sides are marked with greatness according to the state standard scale.

Recommendations for work: sharpen dry or with soap foam or water. To clean the bar from glaring, use water and a brush.
On OSB bond it's better to use sharpening oil for better results!!
These stones are suitable for Blitz, Blitz 360, Kadet, K03, Edge Pro, and knife sharpeners.
