) is a well-known knot
Knot
A knot is a method of fastening or securing linear material such as rope by tying or interweaving. It may consist of a length of one or several segments of rope, string, webbing, twine, strap, or even chain interwoven such that the line can bind to itself or to some other object—the "load"...

 most often associated with its use in hanging
Hanging
Hanging is the lethal suspension of a person by a ligature. The Oxford English Dictionary states that hanging in this sense is "specifically to put to death by suspension by the neck", though it formerly also referred to crucifixion and death by impalement in which the body would remain...

. For a hanging, the knot of the rope is typically placed under or just behind the left ear. When the condemned drops to the end of the rope, the force is supposed to break the neck. The knot is non-jamming but tends to resist attempts to loosen it.

Number of coils

Each additional coil adds friction to the knot, which makes the noose harder to pull closed or open. 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 slip knot
Slip knot
A slip knot is one of two different classes of knot. The most common are knots which attach a line to an object and tighten when tension is applied to the free end of the line...

. Traditionally speaking, thirteen coils is considered a true "hangman's" noose/knot, as anything less might strangle a person inhumanely. The true hangman's noose was designed to snap a person's neck, making death quicker and less painful.

 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."

Other uses

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.
