MinoSharp 220/GB Ceramic Wheel Water Sharpener, Grey/Black
Recommended for sharpening Global knives but not necessarily  those from other manufacturers, this device employs two ceramic  wheels--one coarse, the other fine--to return a dull knife to working  order. Using the sharpener is simple and easy. Fill the wheels'  compartment with water so your blade is continuously washed while it's  being sharpened. Then draw a knife seven or eight times through the  coarse (white) wheel. Then draw your blade seven or eight times through  the fine (pink) wheel to bring it back to life. The sharpener's plastic  handle is shaped so it can be gripped firmly and safely and has a soft,  rubber-like insert for comfort.--Fred Brack
