Karash Double Loop
Karash double loop is a common name for a knot forming two loops. This knot has been a known variant of the Bowline on a bight per the International Guild of Knot Tyers, referred to as ''bowline twist'' or ''twisted collar bowline on a bight''. The knot is also referred to as ''nœud de fusion'' in French references and sometimes called ''Fusion knot'' in English. The name ''Karash double loop'' was introduced by Mike Karash, who re-invented the knot to create makeshift harnesses for rescue operations and popularized it among rescue workers. Applications The knot is used for vertical caving using the single rope technique, particularly by French cavers. It is advertised by the French Federation of Speleology as a safe alternative to the ''bowline on a bight''. Compared to the traditional bunnyears variant of the figure of eight, its loops remain open under load allowing to clip and unclip carabiner A carabiner or karabiner () is a specialized type of shackle, a metal ...

Climbing
Climbing is the activity of using one's hands, feet, or any other part of the body to ascend a steep topographical object that can range from the world's tallest mountains (e.g. the eight thousanders), to small boulders. Climbing is done for locomotion, sporting recreation, and for competition, and is also done in trades that rely on ascension; such as emergency rescue and military operations. Climbing is done indoors and outdoors and on natural (e.g. rock and ice) and artificial surfaces. Professional mountain guides or rock climbing guides (e.g. the UIAGM), were a significant element in developing the popularity of the sport in the natural environment, and remain so today. Since the 1980s, the development of competition climbing and the availability of artificial climbing walls have dramatically increased the popularity of rock climbing as a sport and led to the emergence of professional rock climbers, such as Wolfgang Güllich, Chris Sharma, Lynn Hill and Ca ...

Rope Rescue
Rope rescue is a subset of technical rescue that involves the use of rope, be it steel or cable rope, or more commonly used nylon, polyester, or other type of rope. Kernmantle (kern = core and mantle = sheath) rope as it is called, is available in various types: dynamic (stretches to absorb the shock of a falling lead climber or rescue professional) or static (actually low stretch) which is most commonly used in rescue and industrial rope work. Anchoring includes using specialty anchors, as well as things as simple as a length of chain, cable, rope, or webbing wrapped around a pillar, tree, boulder, or such. They provide the security and a point from which a person or subject (the word ''victim'' has dropped, and changed to ''subject'', due to the negative implications of the term ''victim'') can be belayed. Belaying is the act of protecting the climber, rescue professional, or subject in the event of a fall. Various other devices used, including friction rappel (lowering) devices ...

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 (960–1279 AD) in China, later popularized ...

Loop (knot)
This page explains commonly used terms related to knots. B Bend A bend is a knot used to join two lengths of rope. Bight A bight has two meanings in knotting. It can mean either any central part of a rope (between the standing end and the working end) or an arc in a rope that is at least as wide as a semicircle. "Any slack part of a rope between the two ends, particularly when curved or looped." In either case, a bight is a length of rope that does not cross itself. Knots that can be tied without use of the working end are called knots ''on the bight''. Binding knot Binding knots are knots that either constrict a single object or hold two objects snugly together. Whippings, seizings and lashings serve a similar purpose to binding knots, but contain too many wraps to be properly called a knot. In binding knots, the ends of rope are either joined together or tucked under the turns of the knot. Bitter end Another term for the working end. C Capsizing ...

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] |
Bowline
The bowline ( or ) 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 common bowline shares some structural similarity with the sheet bend. Virtually all end-to-end joining knots (i.e., bends) have a corresponding loop knot. Although the bowline is generally considered a reliable knot, its main deficiencies are a tendency to work loose when not under load (or under cyclic loading), to slip when pulled sideways, and the bight portion of the knot to capsize in certain circumstances. To address these shortcomings, a number of more secure variations of the bowline have been developed for use in safety-critical applications, or b ...

Bowline On A Bight
The bowline on a bight is a knot which makes a pair of fixed-size loops in the middle of a rope. Its advantage is that it is reasonably easy to untie after being exposed to load. This knot can replace the figure-eight loop knot when tying into a climbing harness. It is one of the two tie-in knots that are being taught by the German Alpine Club (DAV), generally being considered secure. Dangers 2011 testing shows that the knot might slip when only one loop is loaded. Cavers and canyoneers ought to fasten their cow-tail carabiner through both loops. Video with genuine ''et voilà!'' ending European cavers widely advocate the use of a figure eight twisted version of the bowline on a bight. Applications This knot can be used to provide a toe hold in the middle of a rope; to make an emergency bosun's chair; and to create an upper rope "block" to make a crude purchase by threading the rope round an anchor point and then back up through the loop. It is sometimes used in sport climbi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Single Rope Technique
Single-rope technique (SRT) is a set of methods used to descend and ascend on the same single rope. Single-rope technique is used in caving, potholing, rock climbing, canyoning, roped access for building maintenance and by arborists for tree climbing, although to avoid confusion in the tree climbing community, many have taken to calling it "stationary" rope technique. Single-rope technique is used in contrast to double-rope technique (DRT), also known as moving-rope technique. Historical developments In the 1930s, as caving became increasingly popular in France, several clubs in the Alps made vertical cave exploration an outdoor sport. During World War II, a team composed of Pierre Chevalier, Fernand Petzl, Charles Petit-Didier and others explored the Dent de Crolles cave system near Grenoble, France, which became the deepest explored cave in the world (-658m) at that time. The lack of available equipment during the war forced Pierre Chevalier and the rest of the team to dev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French Federation Of Speleology
The French Federation of Speleology (, FFS), is a French organisation that represents all persons practicing or studying caving and canyoning and promotes the study and conservation of caves. It was formed in 1963 by the amalgamation of two organisations, the (CNS), or National Committee of Speleology, and the (SSF), or Speleological Society of France. History Société de spéléologie (1895–1914) Founded by Édouard-Alfred Martel in 1895, the was the first organisation of its kind in Europe. Between 1895 and 1900 the society published a journal entitled ''Spelunca''. The society folded in 1914 at the start of World War I. Spéléo-club de France (1930–1936) After the First World War, French speleology was represented mainly by Norbert Casteret and Robert de Joly, who continued the interrupted work of Martel's . On 18 March 1930, an organisational meeting led to the creation of the , whose headquarters were set up at Montpellier, in the headquarters of the Department of ...

Figure-eight Loop
Figure-eight loop (also figure-eight on a bight, figure-eight follow-through, figure-eight retrace, Flemish loop, or Flemish eight) is a type of knot created by a loop on the bight. It is used in climbing and caving. The double figure eight is used to put a loop in the end of a rope, or around an object. It is relatively easy to tie and is secure, but can become difficult to untie after heavy loading, and can jam badly in any rope type. Tying methods On a bight A figure-eight loop is created by doubling the rope into a bight, then tying the standard figure-eight knot. In climbing, this knot is used to save time when repeatedly attaching the rope to climbing harnesses, using locking carabiners, such as when a group of people are climbing on the same top-rope. Follow-through Alternatively, to tie the knot directly around an object, the follow-through method must be used. * Tie a regular figure eight knot with a significant amount of extra tail. * Loop the tail around the o ...

Carabiner
A carabiner or karabiner () is a specialized type of shackle, a metal loop with a spring-loaded gate used to quickly and reversibly connect components, most notably in safety-critical systems. The word is a shortened form of ''Karabinerhaken'' (or also short ''Karabiner''), a German phrase for a "spring hook" used by a carbine rifleman, or carabinier, to attach his carabin to a belt or bandolier. Use Carabiners are widely used in rope-intensive activities such as climbing, fall arrest systems, arboriculture, caving, sailing, hot air ballooning, rope rescue, construction, industrial rope work, window cleaning, whitewater rescue, and acrobatics. They are predominantly made from both steel and aluminium. Those used in sports tend to be of a lighter weight than those used in commercial applications and rope rescue. Often referred to as carabiner-style or as mini-biners, carabiner keyrings and other light-use clips of similar style and design have also become popular. Most ar ...
