I bake for some time often bread itself and was looking for a cheap alternative to an electric food slicer. I am not at all clear came with this cutting aid. I regularly clean cut into the plastic and had after half a bread already my right to return forfeited abruptly. In the end I had quite a few pieces of plastic with the clippings. Since I was finished with that thing. Maybe I'm too clumsy, maybe it was the wrong knife. Anyway, I have now disposed of it :-(
