My bread knife already crumbled freshly baked breads along very. That's why I bought this knife sharpener. That it is to sharpen scissors, even scythes and lawnmowers knife, has led me along with low price to buy. The negative reviews regarding small damage to the sharpened cutting I finally classified as irrelevant, since those complaints were also cited in more expensive knife sharpeners. Basically, I was not a sharpener, in which no man complained precisely this damage. Perhaps one can not achieve sharpening without damaging the cutting surfaces? And maybe the extent of the damage is not only the sharpener, but also on the quality of the cutting surfaces? My bread knife cuts by using the sharpener anyway excellent. And a pretty blunt scissors transformed after three In pulling back to a very capable device. If now that the cutting surface is damaged a bit, I will not interfere, because I had the scissors otherwise namely discarded. Also I would have had to buy a new bread knife me. Be sure you should rinse the device after sharpening sharpened, so that one does not introduce small metal chips into the food. I find the sharpener well and can highly recommend it.
However, if very expensive, hundreds of dollars has costing knives and scissors, should perhaps buy sharpener at just the manufacturers of these equipment. The then yes would give a guarantee on the cutting surfaces.
