Abstract
Abstract A safety razor having a handle assembly and a blade mounted thereon is disclosed. The handle assembly includes a gripping portion formed at one end thereof, a surface extending transversely of the center line of the handle assembly to define the other end of the assembly, and another surface for mounting the blade to the handle assembly so that the blade's cutting edge is at an acute angle with respect to the transverse surface and so that no part of the blade extends beyond the other end of the handle assembly.
