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.

Great knot and here is an alternative way to tie it
This is a really nice graphic of the knot. Who does your diagrams? You? It’s awesome. I wish all knot diagrams were like this.

Thanks Mike, I do the infographics myself. I would agree that some knotting directions seem to be written by people who don’t actually use knots very much.

Hi Clarke, Thanks for including this useful pioneering knot! When starting a lashing on the vertical spar with heavier poles, tying a constrictor provides extra support and a measure of assurance that the lashing won’t slip down when substantial weight is applied. http://scoutpioneering.com/2013/02/25/favorite-pioneering-knots-constrictor/
