Naniwa Chosera recommended stones set (4+1)

Naniwa Stones (known as NANIWA CHOSERA in the Japanese market) are a series of Japanese water sharpening stones produced by the Naniwa company for professional use, boasting an extended operational lifespan.

What sets the Professional Stones series apart from other sharpening stones produced by Naniwa is the increased abrasion resistance of the abrasive surfaces, significantly enhancing productivity during prolonged use and when handling large volumes of sharpening tasks.

Similar to the Sharpening Stones series, the Naniwa Stones (CHOSERA) series is designed to address diverse tasks such as grinding (repair), sharpening, and polishing (finishing) items made of complex alloy tool steels, high-carbon stainless steels, as well as high-carbon corrosion-resistant steels with enhanced wear resistance. Examples of such items include prestigious kitchen, hunting, tactical, and utility knives.

The abrasives used in Naniwa's production are a highly technological product that incorporates complex bonding compositions and composite abrasive grains.

Japanese synthetic abrasives in the Professional Stones series by Naniwa allow for optimal results with minimal effort and time investment. Additionally, this series of sharpening stones exhibits maximum wear resistance and the highest density of abrasive grain edges per unit area of the stone's working surface compared to all other existing synthetic abrasives.

The combination of characteristics such as exceptionally high abrasive efficiency (Naniwa's abrasives are leading in this parameter compared to other manufacturers), excellent wear resistance, and the extreme hardness of the surface of Naniwa Professional Stones ensures the stability of the working surface during operation, earning well-deserved recognition among practicing specialists and professionals.
