In each of the illustrated hand tools, each blade is secured to a tang in the form of a strip of carbon steel, the whole tank being sheathed in plastics material to form the shank and handle. In one embodiment each blade is formed by a strip of carbon steel integral with the tang, and on which a blade edge has been formed, the width of the strip in the blade being, in general, less than that of a conventional blade but having a backing of plastics material molded along the strip to make up its width. |
