Will the ChefsChoice Model 110 cause excessive wear to my knives?
No. Ninety-eight percent of your sharpening takes place in Stages 2 and 3. The diamonds in these stages are very fine and only remove micro-amounts of metal. In fact, when compared to other sharpening methods, the Chef’sChoice Model 110 removes much less metal. There is no other way to sharpen and remove less metal.
