The musical egg slicer takes me back....

I would take the claims of playing Amazing Grace with a pinch of salt, unless the slicer had been customised, but I always thought that it would in fact be possible for a skilled engineer to make a working egg-slicer which also doubled as a musical instrument.

The problem is that each wire would have to be individually tuneable, in the standard egg-slicer it is one continuous length of wire, so individual tuning is out of the question...
