The Smith wire cutter is a type of surgical instrument designed specifically for cutting surgical wires, commonly used in orthopedic and dental procedures. The length, 16 cm (6 1/4 inches), indicates it’s a medium-sized tool, providing a balance between reach and control. The "TC" stands for tungsten carbide, a very hard and durable material used in the cutting inserts to ensure long-lasting sharpness and high cutting efficiency.
