In the premium sharpening stone market, Naniwa’s “Chosera” and “Professional” lines are household names. However, the brand also produces a lesser-known, almost enigmatic series designed for a very specific purpose: the DUO 09 CCD E 18 Hot.

This results in a polished, consistent bevel without micro-chipping.
