Will the ChefsChoice Model 120 cause excessive wear to my knives?
No. Ninety-eight percent of your re-sharpening takes place in Stage 3. The ultra-fine, flexible abrasive in this stage removes only microscopic amounts of metal. In fact, when compared to other sharpening methods, the Chef’sChoice 120 removes much less metal. There is no other way to sharpen and remove less metal.
