1. A hand tool comprising two cooperating interconnected members movable pivotally towards and away from each other, each said member comprising an elongate body of plastics material, a composite metal strip extending through said body, said strip having a tang-portion encased in the plastics body at one end thereof to form a handle and a blade-edge portion embedded in the plastics body at the other end thereof to form the blade, the composite metal strip comprising a main strip of high quality steel on which a durable blade edge has been formed, and a reinforcing strip of relatively inferior quality steel which has been superimposed upon and bonded to the main strip of metal.

2. A hand tool comprising two cooperating interconnected members movable towards and away from each other by handles connected thereto, each member comprising a main strip of metal having at one end a cutting-edge portion and at the opposite end a tang-forming portion, the metal being selected from the group consisting of carbon steel and stainless steel, a reinforcing strip of metal superimposed upon and bonded to the main strip to strengthen the main strip, the metal of the reinforcing strip being different from that of the main strip and being selected from a group of metals of lower cost than the metal selected for the main strip, and a body of plastics material molded on to the main and reinforcement strips to form a handle on the said tang-forming portion, the body extending from the handle along the cutting-edge portion.
