The bottle sling knot has been around for centuries. This ancient method of forming a sling for the neck of a jug or bottle this knot was described in detail by the Greek physician Heraklas in his first century book on surgical knots and slings.
The bottle sling can be used to create a handle for a container with a slight flare or collar. In a doubled form known as a hackamore it can also form an improvised emergency bridle for a horse; the central parts acting as a bit, the knot’s outer loop on the muzzle, and the other passing under the jaw.
With a little practice you’ll be able to master this interesting, useful knot.
