An ergonomic and high-performing update to the indispensable tying tool. The powder coated ergonomic handle rests perfectly between the thumb and fingers, while the spring steel spool holder allows for easy adjustment in tension by changing the pressure applied by the feet. The tube is made of double radius polished tungsten - better than ceramic! It's also designed with versatility in mind: the high gauge works well when tying small flies, and the tube is long enough to tackle large patterns as well. This bobbin will not work with a standard bobbin threader it need the extra long bobbin threader from Loon.
