Naniwa Professional Stones (or for the Japanese market NANIWA CHOSERA) is a series of Japanese water stones produced by Naniwa, which has an increased working life for professional use.
From other sharpening stones manufactured by Naniwa, the Professional Stones series is distinguished by increased wear resistance of abrasive stones, which can significantly increase productivity during long-term use and large volumes of sharpening. Like the Sharpening Stones series, the Naniwa Professional Stones series is designed to solve complex tasks of roughing (repairing), sharpening and polishing (finishing) products made of complexly alloyed tool steels, high-carbon stainless steels, and high-carbon corrosion steels with increased wear resistance. Products made from such steels include samples of expensive knife products - prestigious chef's, hunting, tactical, utility knives, etc.
Naniwa abrasives is a high-tech product that uses complex complex bonds and compound abrasive grains. Starting with stones of 5000 grit, special substances are added to the bundle of bars, which provide a chemical effect on the surface oxide of the knife metal, thereby enhancing the polishing effect of the approach. Those. when working with fine-grained Naniwa Professional Stones, the classic cutting of blade steel with an abrasive is replaced by a chemical-mechanical process of processing its surface.
