These pliers are designed for jewelry making and wire wrapping, specifically for creating loops, bends, and coils in wire. Stepped Jaw: The stepped, round jaw features multiple diameters (e.g., 4.7mm, 3.5mm, 2.2mm) for creating loops of various sizes. Flat Jaw: The flat jaw provides a stable surface for bending and shaping wire, and in some designs, it may also be used to prevent marring of the wire during shaping. Application: Commonly used to form bails, jump rings, ear wires, and other components in jewelry design. Gently used, in excellent condition.
