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?
