Love letter to the constrictor
This is my love letter to the constrictor. I propose that it is the multitool of knots.
First of all, it is easy to tie and is not too rope-hungry. It can also be quickly and elegantly tied on the bight.
I've noticed a tendency to speak of it as a permanent knot you'll have to cut off if subjected to any load. This ignores that fact that it takes a slipped form very well, which alleviates those concerns. Most of the constrictors I tie are slipped.
Now, I am not advocating doing this instead of learning the proper knots, but if for the sake of argument, you had suddenly forgot all your other knots, you could still:
- Temporarily or permanently hitch a rope to a round object
- Make a quick-release fixed loop (in paracord at least, tying a constrictor around the standing line will give you a loop you can adjust the length of, then "snap" shut similar to a capstan loop)
- Approximate a bottle sling knot: Make a constrictor around the bottle's neck, and pass the free end under both wraps, opposite the crossing point of the knot before tightening
- Tie lanyards to various objects; simply tie a constrictor at both ends
- Tie bundles together
- Make a light-duty square lashing (the constrictor and transom knot are topologically identical)
- Emulate a zip tie, or a hose clamp in some material
- Close a bag
- Tie a stopper knot or a sliding toggle, by making a constrictor around one or two strands of another rope respectively.
And whatever else I'm forgetting.
Does anyone else hold a particular knot in especially high respect?
