[@ Peik] - So you're saying you sliced watermelons with a personally designed Guillotine? Must've been one helluva a height to drop that blade! I imagine that it might probably work well with slicing rows of oranges, melons, or tough fruits like durian.

It wasn't height, really, the thing worked on a pivot principle. You pulled the blade up with the help of a rope and when let go it moved in a half-circle motion, cutting whatever was in the half-circle killzone underneath.
