Those recommendations aside, Constrictor knots do function best on fully convex objects. In situations where the object leaves gaps under the knot and there are no corners, it is possible to finish the Constrictor knot off with an additional overhand knot, in the fashion of a Reef knot, to help stabilize it. If binding around a not fully convex, or square-edged, object arrange the knot so the overhand knot portion is stretched across a convex portion, or a corner, with the riding turn squarely on top of it. The Constrictor and Double Constrictor are both extremely secure when tied tightly around convex objects with cord scaled for the task at hand. If care is taken not to cut too deeply, the underlying wraps will protect the bound object from being marred by the knife. 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.
