While the French Famex razors bear a passing resemblance to the Le Coq "caged head" razors well known to collectors, they are in fact very different beasts. The key to the Famex design is that its fully enclosing and flexible cage enables the user to adjust blade gap with a small twist of the handle which compresses or releases compression of the cage as desired. Fully compressed, the Famex is a relatively mild shave. With a slight twist the Famex becomes much more aggressive. However it is adjusted it is a superb shaver. The handle pictured above I believe to be a L'Essor , not an original.
