Abstract
A shaving unit comprises an open framework to which at least one razor blade is secured by its ends, the razor blade having a cutting edge spaced at a predetermined distance from one surface of the framework which provides a guard surface for the cutting edge. The framework also has supporting surfaces within the boundaries of the framework to which intermediate portions of the razor blade are attached leaving substantial lengths of the razor blade clear of the framework to permit the unimpeded passage of cut hairs and shaving soap past the cutting edge and thence through the open framework.
