This is an excellent knot to use as a ligature, to create a tourniquet, or bind a broken limb perhaps? It’s also the knot I use to tie fender lines since the commonly used clove hitch easily comes undone and tends to slide along the rail out of it’s intended position, whereas the strangle knot tightens the more it’s pulled.

Another use I make of it is tying hanks of ropes up for storage.
