The instructions say the razor is 22k gold plated (I believe this example is nickel plated). Shake vigorously to 'sharpen.' Manufacturer: The address on the instruction sheet is SHAVETY FIRST CORPORATION, 271 Fifth Avenue, New York 16, N. Y. Type: Single-Edge Country: USA Patent: U.S. 2337595, 28 Dec 1943, filed 7 Jan 1943. James C. Friel, Beverly, Mass. and U.S. 2359028, 26 Sep 1944, filed 24 Feb 1944, same inventor, New York, N.Y. Comment: Uses a standard double-edge blade, but in use only one edge is exposed (and sharpened). A descendent of the DeHaven (a.k.a. De Haven) and Pilliod. May also have been called the Shake Shave.
