The double end jaws make this style tong the most economical in our line. If teeth become burred or dull from long use, simply reverse them end for end. This feature doubles the life of the tool. All components of Armstrong Chain Tongs are chosen to provide a durable, long-lasting tool, strong beyond need, and with the professional appearance experienced users expect from their pipe tools.  Jaws are drop forged from alloy steel, chain tong jaws are carefully milled and heat treated. They are tested for strength and wearability and finished in a bright red baked-on enamel. Pipe capacity, in both inches and millimeters, is forged into sides of each jaw.  Only selected alloy steel is used for the handles to provide the correct degree of stiffness without risking brittleness. After forging, handles are grit blasted and oil coated.  Flat link chains, the key to any top quality tong, are heat treated and proof-tested under quality control. Each chain is shipped with a lead seal indicating it has been tested to 2/3 of its cataloged breaking strain.
