The Stonfo #2 Thick Tube Adjustable Tension Fly Tying Bobbin is desinged for larger thread spools and tying with heavier fly tying threads allowing you to bear down a bit harder. Like the Stonfo #1 Adjustable Tension Fly Tying Bobbin, the #2 uses a sliding tension bar to easily adjust the bobbing tension to match your personal preferences and the strength of the thread you are using.
