These Fumitaka Hara designed MinoSharp ceramic water sharpeners are the ultimate sharpening tool for Global knives and for that matter any other Japanese blade.
High quality knife blades have a unique finish in that the blade edge is slim and very sharp and should be sharpened with an appropriate tool. This sharpener is easily used by simply adding water to the reservoir compartment of the sharpener and running the knife through the special ceramic wheels in sequence to restore and maintain the original razor sharpness of your Global knife. These sharpeners have been tested and approved by the international and foremost authority on knife sharpening techniques, CATRA based in Sheffield England. Spare ceramic wheels are also available and easily replaced.
Very fast, very safe, very simple.
