The hangman's knot or hangman's noose (also known as a collar during the Elizabethan era) is a well-known knot most often associated with its use in hanging a person. For a hanging, the knot of the rope is typically placed under or just behind the left ear, although the most effective position is just ahead of the ear, beneath the angle of the left lower jaw. The pull on the knot at the end of the drop levers the jaw and head violently up and to the right, which combines with the jerk of the rope becoming taut to wrench the upper neck vertebrae apart. This produces very rapid death, whereas the traditional position beneath the ear was intended to result in the mass of the knot crushing closed (occluding) the neck arteries, causing cessation of brain circulation. The knot is non-jamming but tends to resist attempts to loosen it.

Number of coilsEdit
Surviving nooses in the UK show simple slipknots that were superseded in the late 19th century with a metal eye spliced into one end of the rope, the noose being formed by passing the other end through it. The classic hangman's knot was largely developed in the USA, the heavy mass of the knot intended to crush blood vessels in the neck and if tightened beneath the jaw, to lever the head to one side. Filmed hangings of war criminals in Europe after World War 2, conducted under US jurisdiction, show such knots placed in various places, including at the back of the neck.
Each additional coil adds friction to the knot, which makes the noose harder to pull closed or open. Grover Cleveland, when Sheriff of Erie County, performed 2 hangings, and was advised by a more experienced Sheriff to grease the rope with tallow and run it through the knot a few times to ensure rapid closure with the drop. The number of coils should therefore be adjusted depending on the intended use, the type and thickness of rope, and environmental conditions such as wet or greasy rope. Six to eight loops are normal when using natural ropes. One coil makes it equivalent to the simple running knot.
The number thirteen was thought to be unlucky. Consequently, in myth, if not in actual practice, thirteen coils were found in a hangman’s noose, a foreboding sign for those convicted to be hanged.
Woody Guthrie sings of the hangman using thirteen coils:
Did you ever see a hangman tie a hangknot?
I've seen it many a time and he winds, he winds,
After thirteen times he's got a hangknot.
A variation of this knot is used in fishing and is called the Uni-knot. It is used to tie fishing line to terminal tackle, join two pieces of line, or for snelling hooks. It is especially useful when used with slick braided line as more coils can be added to increase the friction of the knot and will not let the knot pull out. It is also useful in that the knot can be pulled down tight to the lure or it can be left with a larger loop that gives the lure more freedom of movement. The hangman's noose can also be used in boating to secure an eyelet on a rope or sheet without splicing it.
