摘要： A hand-held cutting tool can make repeated precision cuts into hard materials after being repeatedly exposed to highly corrosive and oxidizing conditions. The cutting tool comprises a pair of interactive stainless steel complementary members, each member having a handle portion at one end and a cutting portion at the other end. The cutting portion comprises a hardened tool-steel insert forming the tool's cutting edge. The surface of each member is hard chrome plated except for the hardened tool-steel cutting edge. Each member comprises a recessed portion of complementary size and configuration to accommodate interaction between the members. A washer resides between each member to accommodate unwanted space and a screw is used to hingedly join each member together so that the cutting edges are aligned in an opposed fashion directed toward each other. The tool's cutting portion, including both cutting edges are coated with a refractory material.
