The English invented the
shifters, or an adjustable
spanner which is referred to
en France, as the clé à molette,
or, occasionally un croissant.

Le croissant is a crescent
shaped pastry which took
its name and shape from
the moon as seen on flags
of many Islamic nations.

A Molette or Roulette Dentée
is a wheel with teeth, cogs, as one
sees on the British Wrench. This
is the typical tale of two cultures,
industrialisation versus realisation.
