FEATURES:
[ULTRA-HIGH FLATNESS(≤0.01mm)]: Long-edge knives can perfectly fit the flat surface of the sharpening stone, thus ensuring that even the narrow, elongated cutting edges are properly ground. This is a fundamental condition for high-end tool sharpening,making it more suitable for professional sharpening markets such as workshops and clubs. You can also use this CBN sharpening stone to hone your conventional whetstones and grinding wheels.
[WHY CBN NOT DIAMOND]: This is determined by the properties of the bond itself. Electroplating bond is different from resin and metal bond. In the work of electroplating bond, there is no buffer and heat-conducting substance such as the bond between the abrasive particles,making it easier to generate high temperatures. If diamond is used, the carbon element will react with the iron element, thereby affecting the quality of the cutting tool and causing the diamond sharpening stone to lose its sharpness, making the sharpness deteriorate gradually. However, using CBN abrasive will not have such a problem.
