Re: Sharpening Ceramic Knives
YES it is much more difficult to sharpen ceramic blades due both to the extreme hardness AND the tendency of creating micro-chips on the edge. BUT it is not impossible to both repair small damage or chipping and also to polish and refine the edge to a very high level of sharpness.
The ideal tool of course is a powered diamond wheel with a minimum of 1,000 grit diamond. Even finer grits can be used to truly polish the edge. However, no one I know, except myself, is willing to purchase this kind of equipment.
