The knife set appears to work fine. There is one serious ommision however, not of the implement itself but in the cursory information provided. Nowhere in the instructions included is there a mention of what each set of blades is intended for. In attempting to slice my homemade sourdough loaf with a thick crust, choosing the wrong blades for cutting through the tough crust, the blade slipped off the loaf, missing my thumb by fraction of an inch. Swapping the blade set made slicing the loaf a breeze.
