I didn’t realise at the time but a shoveler can be cut from a enneamond. The waste produces another shape which I have called a coot. Further cuts produce a cygnet (more on this later perhaps).

The shoveler and coot in combination can produce a regular hexagon. Other permutations are possible.

It is interesting to note that the shoveler has 8 sides, the coot 7 and the cygnet 9.
