Hangman's knot: Difference between revisions

The '''[[Execution (legal)|hangman]]'s knot''' or '''hangman's noose''' (also known as a '''collar''' during Elizabethan times) is a well-known [[knot]] most often associated with its use in [[hanging]]. For a hanging, the knot of the rope is typically placed under or just behind the left ear. As the blow when the condemned drops to the end of the rope is supposed to break the neck (for modern "long-drop" hangings), this knot can add additional striking force against the head and neck. The knot is non-jamming but tends to resist attempts to loosen it.

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; more may be used on nylon ropes. One coil makes it equivalent to the simple [[slip knot]].

According to tradition, the noose used in executions had six to eight coils. It is an unfounded urban legend that the hangman's noose is supposed to have 13 coils. Furthermore, an [[urban legend]] exists in the [[United States]] that it is a criminal offense to possess a noose made with exactly thirteen coils. These legends may have come about from scaffolding that was ten feet tall and having standard 9 inch risers for steps thus creating 13 steps; the number [[13 (number)|13]] [[Triskaidekaphobia|being considered unlucky]].

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. See also [[uni knot]]. The hangman's noose can also be used in boating to secure an [[eyelet]] on a rope or sheet without splicing it.
