The constrictor knot is a way of making a secure, temporary or semi-permanent binding (it’s a good temporary whipping for a rope, closing a bag, or holding a punch of poles together.)
A close cousin of the clove hitch the constrictor knot adds an additional crossing of the ends under the full wrap. It’s easy to learn with a little practice.
Once drawn up tight the constrictor knot jams and may have to be cut to release it. It has incredible binding power and once you’ve mastered tying the knot you’ll find any number of uses for it.
