Safety razor : ウィキペディア英語版
Safety razor

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 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).
Plastic disposable razors, and razors with replaceable blade attachments, are in common use today. Razors commonly include one to five cutting edges (but sometimes up to seven).
