519,552. Making glass razor blades. FORD, H. Nov 16, .1938, No. 33276. Drawings to Specification. [Class 56] [Also in Group XIV] A razor blade is made from hardened glass. The edges of the blade are first ground and the blade is then hardened, the edges being kept at a sufficiently low temperature during heating to prevent them from losing their cutting-edge.
