Abstract
Abstract A means and apparatus for applying lather and moisture to a shaving surface in advance of the razor blade so that the shaving operation can be conducted in a single stroke. In one embodiment the lather is provided by a device which attaches to the handle of a conventional safety razor. This device is wetted to impart a lathering composition. In a second embodiment, the lathering device is integrally joined to a razor handle comprising a water reservoir so as to supply moisture to a confined soap cake and thereby provide lather to the shaving surface.
