The Stonfo Steeltech Bobbin is a premium bobbin holder engineered for serious tying performance. Made entirely from stainless steel and weighing 1.25 ounces, this tool provides excellent thread tension and balance for clean, consistent wraps. The ergonomic structure includes two tension‑adjust knobs and a central shaft for spool stability, while the hardened steel bush at the tube stop prevents thread fraying under heavy use. Ideal for dubbing loops or high‑precision tying where control matters.
