MinoSharp's award-winning Plus 3 MC-550 wet sharpener from Global.
All you have to do is fill the knife sharpener with a little water and make a few strokes with the knife through the different wheels and you'll be as sharp as new.
The wet sharpener has three grinding wheels in different sizes:
coarse (120 grit)
medium (240 grit)
fine (600 grit).
