Abstract
Abstract A knot tying tool having an elongated, resilient body provided with a pair of transverse inner slits and a pair of transverse outer slits is especially adapted for use in typing a blood or barrel knot for joining a plurality of fishing line leaders. The two inner slits which are disposed in a converging relationship each receive and retain a stretch of their respective leader such that during the process of tying the knot the leaders are withdrawn from the slits and come together as the knot is pulled tight. The free ends of the stretches have in the meantime, been retained in the two outer slits while the knot is being formed and are subsequently removed therefrom after the knot has been completed.
