The Loon Ergo Bobbin is the perfect tool for maximising your fly-tying capacity. As the name Ergo suggests, the thumb and forefinger pad are comfortable and ergonomic to hold for hours of tying. The double-radius stainless steel barrel protects even the lightest thread from nicks and wear. The Egro Bobbin incorporates Japanese spring steel arms for an even and easily adjustable amount of tension. If you need a workhorse bobbin for your fly-tying kit, check out the Loon Ergo Bobbin.
