Constrictor Knot (Twisting Method)

Twist the rope to form a loose figure 8. Fold the loops down around the center to form the Constrictor Knot.

Uses: The Constrictor Knot (ABOK # 1188, p 216.) deserves to be much more widely known and used. It is an excellent quick temporary whipping for a fraying rope's end and can be used to keep a rope's end together while it is being whipped. It securely ties the neck of a sack or bag; it has been used as a temporary hose clamp; and it can be used to hold items together for gluing.

Alternatives: In addition to the Twisting Method, the Constrictor Knot can be tied by theFolding Method, and by Threading the End when tying this knot round a rail or bar.

Using the Twisting Method: The Twisting Method is ideal for short lengths, e.g., when using a piece of twine to secure a fraying rope's end. However, the method cannot be used when using a longer piece of rope or when the rope has to be first passed around the object to be tied.

Disadvantages: It fails when tied against a flat surface - it requires a curved surface for the binding turn to grip the Half Hitch.

Release: The knot can be very hard to undo - cutting the knot can be the only resort. When this is necessary, the binding strand should be cut over the other constrictor strands, using them to protect your rope.

Rope Size: The pictures here show the rope tied in large diameter rope. This is only for the photography. It is normally tied in twine or other small diameter line.
