Made to be used with Global knives and european knives.
The sharpener consists of two ceramic wheels. No1, white, is course and No2, pink, is fine for a complete sharpening process. Due to the fact that the sharpening groove is not parallel, the oblique angle of the ceramic wheel is able to restore the razor sharpness of your knife.
This Global ceramic water sharpener has been tested and appoved by CATRA - the foremost authority on knife sharpening techniques, based in Sheffield.
