A couple of days ago we had a look at Mr Nordskog’s oddly shaped safety razor, which was patented a hundred years ago. One of the patens which cites Mr Nordskog’s patent is assigned to American Safety Razor Company. Filed by Clemens A Iten in 1984. The later invention appears to be a recreation of the former patent in the shape of a multi-blade, disposable, cartridge monstrosity. One straight edge, one convex edge. No rounded edge on the short side though.
A cap and platform having an elongated longitudinally curved surface with a flexible shaving blade between them seem to be one of the major claims in the patent. Other claims goes into the construction of the cartridge.
The patent in its entirety can be read at Google Patents.
