Disposable safety razors were patented from time to time in the past. Usually they were just a regular safety razor made from cheap or disposable materials. Sometimes they were a minor stroke of genius. Sometimes they were plain odd. Mr Foltis’ safety razor made from bent sheet metal is one of the later two.

An important object of the invention is to provide an inexpensive safety razor having an integral razor blade of small size whereby the entire razor must be disposed of after the blade becomes too dull for shaving purposes.
