Abstract: In a hand held tool for tying a knot connecting a fishing line to the eye of a fishhook, an elongated generally planar body, is provided with a fishhook supporting forwardly projecting tube and a pair of resilient fins diverging from its rearward end. A laterally projecting lug having a transverse slot holds an intermediate portion of the line. The line free end, after being threaded through the eye of the fishhook, is entrained transversely across the tips of the diverging fins and wrapped a plurality of times about the tube and extended through the opening formed by the fins and line and secured by a slot at the juncture of the fins. The knot and fishhook is then removed forwardly off the tube and the knot tightened against the eye of the fishhook.
