Eversharp Fashion Razor
The Eversharp Fashion Razor (a.k.a. Schick H1) was made between 1947 and 1953 as a razor for the Ladies. It is however one of the best razors ever made. It takes normal injector blades as well as Twin blades. The Eversharp Fashion Razor was one of the inspirations for the Bunny V3 injector razor.
I have not been able to find a patent for this razor design. If you see one, please let me know.
