My invention has for its object the provision of a simple and efficient mechanism whereby blades of safety razors may be sharpened. One object of the invention is to provide a compact and simply arranged machine, which may be operated by one hand while held in the other hand or permanently secured to a fixed support. The invention seeks to provide a machine for the stated purpose which, when in use, will act upon one face of the blade at the edge thereof for a definite period and will then automatically reverse the blade so that the opposite face will be acted upon, a further object being to apply the sharpening action diagonally along the blade with die lines of action on one face of the blade crossing the lines of action on the other face of the blade. Another object of the invention is to provide means whereby when the blade is reversed it will be prevented from coming into forcible contact with the honing or sharpening member and chipping, splitting or other injury of the blade will be avoided, and a still further object of the invention is to provide means whereby the blade will be reversed after being lifted from the honing or sharpening member and prevented from turning as it returns to the normal position in engagement with the sharpening or honing member.
