A safety razor is a shaving implement with a protective device positioned between the edge of the blade and the skin. The initial purpose of these protective devices was to reduce the level of skill needed for injury-free shaving, thereby reducing the reliance on professional barbers for providing that service and raising grooming standards. The term was first used in a patent issued in 1880, for a razor in the basic contemporary configuration with a handle attached at right angles to a head in which a removable blade is placed (although this form predated the patent). 1847 William S. Henson. patented a "comb tooth guard or protector" which could be attached both to the hoe form and to a conventional straight razor. May 1880 by Fredrik and Otto Kampfe of Brooklyn, New York, improved the 'safety razor' and it differed from the Henson design in distancing the blade from the handle by interposing,, "a hollow metallic blade-holder having a preferably removable handle and a flat plate in front, to which the blade is attached by clips and a pivoted catch. 1900 King C. Gillette had the revolutionary idea of disposable blades so thin and so strong they were deemed impossible to forge by MIT-trained scientists. By 1901, he’d proven them wrong with his breakthrough innovation. The success of Gillette's invention was largely a result of his having been awarded a contract to supply the American troops in World War I with double-edge safety razors as part of their standard field kits (delivering a total of 3.5 million razors and 32 million blades for them). The returning soldiers were permitted to keep that part of their equipment and therefore easily retained their new shaving habits. The subsequent consumer demand for replacement blades put the shaving industry on course toward its present form with Gillette as a dominant force. Plastic disposable razors and razors with replaceable disposable blade attachments, often with one to three cutting edges (but sometimes with four and as of recently, five cutting edges), are in common use today.
