The hangman's knot [1] or hangman's noose [2] (also known as a collar during the Elizabethan era) is a knot most often associated with its use in hanging a person.
This knot was typically used as a method of capital punishment. The pull on the knot at end of the gallows often resulted in a cervical fracture. Another method intended to result in the mass of the knot crushing closed (occluding) neck arteries, causing cessation of brain circulation, which was not always rapid. The knot is non-jamming but tends to resist attempts to loosen it.
Surviving nooses in the United Kingdom show simple slipknots that were superseded in the late 19th century with a metal eye spliced into one end of the rope, the noose being formed by passing the other end through it.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 United States. Filmed hangings of war criminals in Europe after World War II, conducted under US jurisdiction, show such knots placed in various locations.
Each additional coil adds friction to the knot, which makes the noose harder to pull closed or open. When Grover Cleveland was the sheriff of Erie County, he performed two hangings. Cleveland 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. One coil makes it equivalent to the simple running knot.
Woody Guthrie sings of the hangman using thirteen coils: [3]
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.
The bowline is an ancient and simple knot used to form a fixed loop at the end of a rope. It has the virtues of being both easy to tie and untie; most notably, it is easy to untie after being subjected to a load. The bowline is sometimes referred to as king of the knots because of its importance. Along with the sheet bend and the clove hitch, the bowline is often considered one of the most essential knots.
The overhand knot is one of the most fundamental knots, and it forms the basis of many others, including the simple noose, overhand loop, angler's loop, reef knot, fisherman's knot, half hitch, and water knot. The overhand knot is a stopper, especially when used alone, and hence it is very secure, to the point of jamming badly. It should be used if the knot is intended to be permanent. It is often used to prevent the end of a rope from unraveling. An overhand knot becomes a trefoil knot, a true knot in the mathematical sense, by joining the ends. It can also be adjusted, faired, or mis-tied as a half hitch.
The constrictor knot is one of the most effective binding knots. Simple and secure, it is a harsh knot that can be difficult or impossible to untie once tightened. It is made similarly to a clove hitch but with one end passed under the other, forming an overhand knot under a riding turn. The double constrictor knot is an even more robust variation that features two riding turns.
A shank is a type of knot that is used to shorten a rope or take up slack, such as the sheepshank. The sheepshank knot is not stable. It will fall apart under too much load or too little load.
The marlinespike hitch is a temporary knot used to attach a rod to a rope in order to form a handle. This allows more tension than could be produced comfortably by gripping the rope with the hands alone. It is useful when tightening knots and for other purposes in ropework.
A zeppelin bend is an end-to-end joining knot formed by two symmetrically interlinked overhand knots. It is stable, secure, and highly resistant to jamming. It is also resistant to the effects of slack shaking and cyclic loading.
A slipped half hitch is a knot in which the weight of the load the rope carries depresses the loop sufficiently to keep it in place until the load item is placed in its location. When no longer required the free end may be pulled and draw the loop through and so release the load.
A noose is a loop at the end of a rope in which the knot tightens under load and can be loosened without untying the knot. The knot can be used to secure a rope to a post, pole, or animal but only where the end is in a position that the loop can be passed over.
The sheet bend is a bend knot. It is practical for joining lines of different diameter or rigidity.
The Munter hitch, also known as the Italian hitch, mezzo barcaiolo or the crossing hitch, is a simple adjustable knot, commonly used by climbers, cavers, and rescuers to control friction in a life-lining or belay system. To climbers, this hitch is also known as HMS, the abbreviation for the German term Halbmastwurfsicherung, meaning half clove hitch belay. This technique can be used with a special "pear-shaped" HMS locking carabiner, or any locking carabiner wide enough to take two turns of the rope.
The cow hitch, also called the lark's head, is a hitch knot used to attach a rope to an object. The cow hitch comprises a pair of single hitches tied in opposing directions, as compared to the clove hitch in which the single hitches are tied in the same direction. It has several variations and is known under a variety of names. It can be tied either with the end of the rope or with a bight.
Ashley's stopper knot, also known as the oysterman's stopper, is a knot developed by Clifford W. Ashley around 1910. It makes a well-balanced trefoil-faced stopper at the end of the rope, giving greater resistance to pulling through an opening than other common stoppers. Essentially, the knot is a common overhand noose, but with the end of the rope passing through the noose eye, which closes upon it. It may be multiplied to form a larger knot with more than three bights appearing around the knot. It is the result of implementing a double wall knot in one strand.
The West Country whipping is a quick practical whipping knot, a method of using twine to secure the end of a rope to prevent it fraying. It has several advantages: it can be tied without a needle; it is simple to understand and remember; if the whipping fails, the loose ends can usually be re-tied to temporarily prevent the rope's end from fraying.
West Country whipping was the name given by Biddlecombe in 1848 to this particular practice, but most subsequent seamanship books, including the British Admiralty Manual of Seamanship, have modified the name to West County whipping...I have not seen this whipping used but it has this advantage: if any part breaks it will be a very long while before the whole whipping lets go. The break will be evident and the whipping can be replaced in time.
The halter hitch is a type of knot used to connect a rope to an object. As the name implies, an animal's lead rope, attached to its halter, may be tied to a post or hitching rail with this knot. The benefit of the halter hitch is that it can be easily released by pulling on one end of the rope, even if it is under tension. Some sources show the knot being finished with the free end running through the slipped loop to prevent it from working loose or being untied by a clever animal, still allowing easy but not instant untying.
The bottle sling is a knot which can be used to create a handle for a glass or ceramic container with a slippery narrow neck, as long as the neck widens slightly near the top.
A chain sinnet is a method of shortening a rope or other cable while in use or for storage. It is formed by making a series of simple crochet-like stitches in the line. It can also reduce tangling while a rope is being washed in a washing machine.
A coiling or coil is a curve, helix, or spiral used for storing rope or cable in compact and reliable yet easily attainable form. They are often discussed with knots.
Rope are often coiled and hung up in lofts for storage. They are also hung over stakes in farm wagons and on hooks in moving vans, fire apparatus and linesmen's repair trucks. For such active storage coils must be well made.
A heaving line knot is a family of knots which are used for adding weight to the end of a rope, to make the rope easier to throw. In nautical use, a heaving line knot is often tied to the end of a messenger line, which is then used for pulling a larger rope, such as a hawser. There are several distinct knots which all share the common name, heaving line knot. The monkey fist is a well-known heaving line knot.
