Abstract
Knotting devices for tying incrementally fed string into overhand knots comprises a pair of sturdy opposed angular bills extending uprightly as stalks from a manipulatable shank and the bills including opposed horns laterally extending from the stalks and at a transverse fixed-spacing. Once the string increment is looped around the horns, its trailward-length is resiliently grasped by a retainer means located between the horns to form a noose. Following severing of the string trailward-length, its lead-end is pulled away from the knotting device and the noose slips off the bill horns fore-ends, and finally the retainer means is released thereby resulting in the overhand knot.
