Never underestimate a cheese cutter whose job is to hand cut a wheel of cheese into pieces that are the same size and weight. There is huge responsibility. To make the action easier and quicker a knife can be designed into a package. A tiny turn of the propeller and the cheese will be cut within thin slices.
