The knot will spring apart as soon as the riding turn is cut. If the ends have been trimmed short, or the knot is otherwise hopelessly jammed, it can be easily released by cutting the riding turn with a sharp knife. The use of a pick, marlinespike, or some other tool able to be forced between parts can help. If the ends are still long enough, it may be possible to untie by pulling one end generally parallel to the bound object and a bit up away from it, and prying it into the opposite end's part to open the knot. Noted master- rigger Brion Toss says of the Constrictor, "To know the knot is to constantly find uses for it." ReleasingĪ heavily tightened Constrictor knot will likely jam. Constrictor knots can also be quite effective as improvised hose clamps or cable ties. Ĭonstrictor knots can be for used for temporarily binding the fibres of a rope or strand end together while splicing or when cutting to length and before properly whipping the ends. To exert extreme tension on the knot without injuring the hands fashion handles for the ends using Marlinespike hitches made around two rods. The Constrictor knot's severe bite, which makes it so effective, can damage or disfigure items it is tied around. Tied over a hard surface, use soft stretchy line. Tied over soft material, such as the neck of a bag, use hard stiff cord. Made with small-stuff it is especially effective, as the binding force is concentrated over a smaller area. The Constrictor knot is appropriate for situations where secure temporary or semi-permanent binding is needed. To release, tug on the working end so that the bight passes back through the knot. Be sure the bight and ends emerge between the two turns as shown.Pass a bight under the standing part and riding turn, instead of using the end itself.Make a turn around the object and bring the working end back over the standing part.Other methods exist which can be used to tied it in the hand or over the end of the object to be bound. The method shown below is the most basic way to tie the knot. Day relates that, "she had never seen it in Finland, she wrote to me in 1954, but had learned about it from a Spaniard named Raphael Gaston, who called it a whip knot, and told her it was used in the mountains of Spain by muleteers and herdsmen." The Finnish name "ruoskasolmu" ("whip knot") was a translation from Esperanto, the language Ropponen used to correspond with Gaston. Finnish girl scout leader Martta Ropponen presented the knot in her 1931 scouting handbook Solmukirja ("Knot Book"), the first published work known to contain an illustration of the Constrictor knot. The Constrictor knot was described but not pictured as the "timmerknut" ("timber knot") in the 1916 Swedish book Om Knutar ("On Knots") by Hjalmar Öhrvall. Hyatt Verrill illustrated Burgess' Clove hitch variation in Knots, Splices and Rope Work. Burgess copied from Bowling, he changed this text to merely state "when the ends are knotted, the builder's knot becomes the Gunner's Knot." Although this Clove hitch with knotted ends is a workable binding knot, Burgess was not actually describing the Constrictor knot. He wrote, "The Gunner's knot (of which we do not give a diagram) only differs from the builder's knot, by the ends of the cords being simply knotted before being brought from under the loop which crosses them." Oddly, when J. Bowling described it in relation to the Clove hitch, which he illlustrated and called the "Builder's knot". The first known description of the Constrictor knot occurs in Tom Bowling's 1866 work, The Book of Knots where it was called the "Gunner's knot". Regardless of its exact origin, there is little doubt that Ashley popularized the Constrictor knot and led to it being much more well known today than in the past. Although Ashley apparently believed he had invented this knot more than 25 years earlier, research suggests that he was not the originator. First called "Constrictor knot" in Clifford Ashley's 1944 work The Ashley Book of Knots, this knot likely dates back much further.
