The Naniwa Professional line (previously known as the Chosera line) are super hard splash and go stones. These stones are slow wearing, fast cutting and HARD. They have a higher amount of abrasives and less binder than other lines from Naniwa, and are one of the best lines of stones money can buy in our opinion!
