Tying the Double Constrictor Knot Instructions

For these instructions, imagine your working end (the part of the rope you’re actively using) is on the right, and your standing part (the main, stationary section of the rope) is on the left. This knot can be a bit “cordage hungry,” so make sure you have enough slack!

1. First Pass: Take your working end and pass it over the top of the object you want to tie the knot around. Bring the working end to the right-hand side
2. Second Pass: Now, pass the working end over the top again for a second time, but this time, take it to the left-hand side.
3. Third Pass (and parallel alignment): Go underneath the object, bring the working end over again, and pass it to the right-hand side. You’ll notice that where you’ve gone over, this turn should be running parallel to your previous one.
4. Underneath and to the Left: Once those parallel turns are in place, bring the working end through underneath the object and to the left-hand side.
5. Over, Under, and Through: Now for the critical part. You’re going to go over the standing part, then underneath the two turns you just created, and finally, underneath the very back turn as well. You might need to lift those turns slightly to get your working end through.
6. Tuck and Dress: Before you pull the knot tight, tuck the working end underneath the turn on the right-hand side. This is crucial for the knot’s structure.
7. Smart Dressing: Now, gently begin to tighten the knot, making sure to dress it smartly. Don’t pull it too tight immediately! Adjust the knot into the correct position first, then pull it snug.

And there you have it! If you thought the constrictor knot was strong, the double constrictor knot offers an even better, more secure hold. Once dressed smartly and pulled tight, it’s incredibly reliable.

What is the disadvantage of using the Double Constrictor Knot?
