device to remove body hair, modern variant (non-electric)
via Wikipedia infobox
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.
Protective devices for razors have existed since at least the 1700s: a circa 1762 invention by the French cutler Jean-Jacques Perret added a protective guard to a regular straight razor. The first known occurrence of the term "safety razor" is found in a United States patent from 1880 for a razor in the basic contemporary configuration with a handle in which a removable blade is placed (although this form predated the patent).
