Abstract: The tracking characteristics of a fishing fly are improved by a detachable, reversible foil having a rear socket which engages the eye of a fishing hook and a front, angled section which causes the fly to wiggle and to rise or fall depending whether the front section is pointing upwardly or downwardly. The rear lip of the fly contains a socket adapted to engage the eye of the hook and a set of channels extending from the front surface of the foil to the socket for receiving the leader thread. The foil can be readily slid on the thread onto the eye of the hook in either orientation. A portion adjacent the eye of the hooks is tapered to blend into the hook shank for a smooth transition with fly tying materials.

Abstract: A combination bobbin and knot tying tool has a knot-tying element attached to the bobbin. In one embodiment, the element is secured to the rear of the bobbin. In a second embodiment, the front end of the thread tube of the bobbin is tapered to form a knot-tying element. In another embodiment, the barrel of the tool is slidingly mounted on the thread tube of the bobbin and slides from a retracted position rearward of the tip of the thread tube to a forward position in which the conical end of the barrel with its eye receiving cavity is forward of the tip of the thread tube.
