First called "constrictor knot" in Clifford Ashley's 1944 work The Ashley Book of Knots, this knot likely dates back much further [REF].
The constrictor knot was clearly described but not pictured as the "timmerknut" ("timber knot") in the 1916 Swedish book Om Knutar ("On Knots") by Hjalmar Öhrvall [REF].
