Icicle Hitch
An icicle hitch is a knot that is excellent for connecting to a post when weight is applied to an end running parallel to the post in a specific direction. This type of hitch will hold its place even when holding a substantial load on a smooth surface. One can even suspend from a tapered post (such as a marlinspike) with this knot (hence the name "icicle hitch").Brion Toss, ''The Complete Rigger's Apprentice'' (Camden: International Marine, 1998), 55β56. To tie an icicle hitch, bring the working end over the post, front to back, four or five times, working away from the end of the post (and the direction of expected pull). Bring the working end, back to front, alongside the standing end, leaving a substantial bight hanging behind the post. Bring this bight over both ends and over the end of the post. Tighten by pulling both ends perpendicular to the post. The pull on the standing end (running the direction of the post) will tighten the knot as more pull is given. This knot ...

Prusik
A Prusik ( ) is a friction hitch or knot used to attach a loop of cord around a rope, applied in climbing, canyoneering, mountaineering, caving, rope rescue, ziplining, and by arborists. The term Prusik is a name for both the loops of cord used to tie the hitch and the hitch itself, and the verb is "to prusik" (using a Prusik to ascend). More casually, the term is used for any friction hitch or device that can grab a rope (see autoblock). Due to the pronunciation, the word is often misspelled Prussik, Prussick, or Prussic. The Prusik hitch is named after its putative inventor, Austrian mountaineer Karl Prusik. It was shown in a 1931 Austrian mountaineering manual for rope ascending. It was used on several mountaineering routes of the era to ascend the final summit, where a rope could be thrown over the top and anchored so that climbers could attain the summit by prusiking up the other side of the rope. A Prusik made from cord does little or no damage to the rope it is attache ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Klemheist Knot
The klemheist knot or French Machard knot is a type of friction hitch that grips the rope when weight is applied, and is free to move when the weight is released. It is used similarly to a Prusik knot or the Bachmann knot to ascend or descend a climbing rope. One advantage is that webbing can be used as an alternative to cord. The Klemheist is easier to slide up than a Prusik. The klemheist is also a way to attach a snubber to the anchor rope of small boats, with the advantage that it is easy to undo.Eric Vola, ΒLe nΕud Machard et son histoire Β», site du CAF-Marseille, 2015 Sometimes the knot name is misspelled as kleimheist, with an extra i. Technique Make a secure loop of a cord (see Double fisherman's knot) that is definitely narrower than the rope. Wrap from one end around the rope two or three times in a direction that will be down. The loose end is then threaded through the starting end, and carefully tightened to leave the wraps neat. In use, strain must be taken o ...

Tautline Hitch
The taut-line hitch is an adjustable loop knot for use on lines under tension. It is useful when the length of a line will need to be periodically adjusted in order to maintain tension. It is made by tying a rolling hitch around the standing part after passing around an anchor object. Tension is maintained by sliding the hitch to adjust the size of the loop, thus changing the effective length of the standing part without retying the knot. It is typically used for securing tent lines in outdoor activities involving camping, by arborists when climbing trees, for tying down aircraft, for creating adjustable moorings in tidal areas, and to secure loads on vehicles. A versatile knot, the taut-line hitch was even used by astronauts during STS-82, the second Space Shuttle mission to repair the Hubble Space Telescope. Naming The adjustable loop forms of the rolling hitch and Magnus hitch, in addition to being called either of those two names, have also come to be known various ...

Gripping Sailor's Hitch
The gripping sailor's hitch is a secure, jam-proof friction hitch used to tie one rope to another, or a rope to a pole, boom, spar, etc., when the pull is lengthwise along the object. It will even grip a tapered object, such as a marlin spike, in the direction of taper, similar to the Icicle hitch, and it is much superior to the rolling hitch for that purpose. Tying Image:bobmcgrsailorgrip1.jpg, Make 5 turns around the object at opposite side of to the pull direction of the standing part, then cross the standing part to the pull direction and make one more turn Image:bobmcgrsailorgrip2.jpg, Cross back over the standing part in front, as you change the turn direction to opposite the wraps, come through from the back, and pass under the standing part (following the pen in pic).

Knot
A knot is an intentional complication in cordage which may be practical or decorative, or both. Practical knots are classified by function, including hitches, bends, loop knots, and splices: a ''hitch'' fastens a rope to another object; a ''bend'' fastens two ends of a rope to each another; a ''loop knot'' is any knot creating a loop; and ''splice'' denotes any multi-strand knot, including bends and loops. A knot may also refer, in the strictest sense, to a stopper or knob at the end of a rope to keep that end from slipping through a grommet or eye. Knots have excited interest since ancient times for their practical uses, as well as their topological intricacy, studied in the area of mathematics known as knot theory. History Knots and knotting have been used and studied throughout history. For example, Chinese knotting is a decorative handicraft art that began as a form of Chinese folk art in the Tang and Song Dynasty (960β1279 AD) in China, later popularized in ...

Parallel (geometry)
In geometry, parallel lines are coplanar straight lines that do not intersect at any point. Parallel planes are planes in the same three-dimensional space that never meet. ''Parallel curves'' are curves that do not touch each other or intersect and keep a fixed minimum distance. In three-dimensional Euclidean space, a line and a plane that do not share a point are also said to be parallel. However, two noncoplanar lines are called '' skew lines''. Parallel lines are the subject of Euclid's parallel postulate. Parallelism is primarily a property of affine geometries and Euclidean geometry is a special instance of this type of geometry. In some other geometries, such as hyperbolic geometry, lines can have analogous properties that are referred to as parallelism. Symbol The parallel symbol is \parallel. For example, AB \parallel CD indicates that line ''AB'' is parallel to line ''CD''. In the Unicode character set, the "parallel" and "not parallel" signs have co ...

List Of Hitch Knots
A hitch knot is a type of knot used to secure a rope to an object or another rope. It is used in a variety of situations, including climbing, sailing, and securing loads. Hitch knots are classified based on their ability to be tightened or released, their resistance to slipping, and their strength. Some common types of hitch knots include the fisherman's knot, the water knot, and the clove hitch. Hitch knots are important because they allow a rope to be securely fastened to an object, enabling the rope to support weight or transmit force. Physical theory of hitches A simple mathematical theory of hitches has been proposed by Bayman and extended by Maddocks and Keller. It makes predictions that are approximately correct when tested empirically.

Marlinspike
A marlinspike (, sometimes spelled marlin spike, marlinespike, or rchaicmarlingspike) is a tool used in marine ropework. Shaped in the form of a polished metal cone tapered to a rounded or flattened point, it is used in such tasks as unlaying rope for splicing, untying knots, drawing marline tight using a marlinspike hitch, and as a toggle joining ropes under tension in a belaying pin splice. Marlinspikes are usually about long, but may reach or more when used for working heavy cables and ropes. They are usually made from iron or steel, whereas fids, similar in shape and function, are formed from wood or bone. The marlinspike may be a separate tool or one item on a pocket knife. Sailors who become proficient at knot tying, splicing, and sewing using the marlinspike are said to have mastered marlinespike seamanship, earning them the right to be known as ''marlin spikes'' or ''marlinspike seamen''. Uses Marlinspikes are used: * As levers to open strands of laid rope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bight (knot)
In knot tying, a bight is a curved section or slack part between the two ends of a rope, string, or yarn.. "Any slack part of a rope between the two ends, particularly when curved or looped." A knot that can be tied using only the bight of a rope, without access to the ends, is described as in the bight. The term "bight" is also used in a more specific way when describing Turk's head knots, indicating how many repetitions of braiding are made in the circuit of a given knot. Bight vs. open loop Sources differ on whether an open loop or U-shaped curve in a rope qualifies as a bight. treats bights and loops as distinct, stating that a curve "no narrower than a semicircle" is a bight, while an open loop is a curve "narrower than a bight but with separated ends". However, ''The Illustrated Encyclopedia of Knots'' (2002) states: "Any section of line that is bent into a U-shape is a bight."

International Guild Of Knot Tyers
The International Guild of Knot Tyers (or IGKT) is a worldwide association for people with an interest in knots and knot tying. Formation and beginning Officially established in 1982, the founding members were initially drawn together by the 1978 publication in ''The Times'' of an allegedly new knot, the Hunter's bend. The idea for a knotting association of some kind grew from the contact between two people. Des Pawson was a retail manager for a large stationery firm based in Ipswich and a knot craftsman. Geoffrey Budworth was a Metropolitan Police Inspector and knotting consultant. Des first wrote to Geoff on 8 October 1978. They met before the month was over, and if it was not mentioned then the idea of contacting other knotting enthusiasts was raised by Des in a letter dated July, 1980, when he pressed for a suitable venue and suggested The Maritime Trust. Even then, 1981 went by without further development; and this is a source of regret to them both as it was the centena ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
