2 Claims. (Cl. 30-96) My invention relates to safety razors and more side. One of the difficulties encountered with a particularly to a novel device used in combination razor blade is to get the backing member to have with the ordinary safety razor having a backing asmooth surface at the edge.

These depressions and bumps at combination of a cushioning sheet interposed be-- the edge would, if the razor blade were pressed tween the backing member and a blade, this sheet against them, cause distortion at the edge of the being adapted to act as a cushion to equalize the blade so that instead of extending in a direct blade pressure at all points.
