Reuleaux triangle

One application is in making fireplug nuts. usually these are pentagons so
a normal wrench can not remove them, but nuts in the shape of a Reuleaux
triangle are even better. One can manufacture a triagular lever that will
get at the pentagon, but the triangle will just roll.
They exist. i hae seen them in Red Wing Minnesota, and have been told that
they have them in Minneaplois Minn. and Ann Arbor Mich.
