The Renzetti Lead Wire & Tinsel Bobbin is purpose-built for working with heavier materials such as lead wire, tinsel, and other dense tying components. Designed for strength and control, this bobbin features a large-diameter tube that accommodates thicker materials without restriction, ensuring smooth, consistent delivery. The stainless-steel construction provides durability and resistance to wear, while the ergonomic arms maintain even tension for clean, precise wraps. Perfect for streamers, nymphs, and saltwater patterns, it allows tiers to handle tough materials confidently without damaging delicate threads or flattening wraps. Like all Renzetti tools, it's engineered for balance, comfort, and long-term reliability, making it an essential addition for tiers who work across a wide range of fly styles and materials.
