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."

Clove Hitch
The clove hitch is an ancient type of knot, made of two successive single hitches tied around an object. It is most effectively used to secure a middle section of rope to an object it crosses over, such as a line on a fencepost. It can also be used as an ordinary hitch, or as a binding knot, but it is not particularly secure in either application. It is considered one of the most important knots, alongside the bowline and the sheet bend. Usage This knot is particularly useful where the length of the running end needs to be adjustable, since feeding in rope from either direction will loosen the knot to be tightened at a new position. With certain types of cord, the clove hitch can slip when loaded. In modern climbing rope, the clove hitch will slip to a point, and then stop slipping. When tied around a carabiner, the load should pull on the end closest to its spine. With smaller diameter cords, after being heavily weighted it may become difficult to untie. It is also unre ...

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 ...

Figure-eight Knot
The figure-eight knot or figure-of-eight knot is a type of stopper knot. It is very important in sailing, rock climbing and caving as a method of stopping ropes from running out of retaining devices. Like the overhand knot, which will jam under strain, often requiring the rope to be cut, the figure-eight will also jam, but is usually more easily undone than the overhand knot. The stevedore knot is an extension of simple figure-eight knot with an additional turn before the end is finally tightened. Different types Figure-eight loop The figure-eight loop is used like an overhand loop knot. This type of knot can be used in prusik climbing when used in conjunction with a climbing harness, a climbing rope, and locking carabiner designed for climbing, to ascend or descend with minimal equipment and effort. Figure-eight bend The figure-eight bend knot is used to "Rope splicing, splice" together two ropes, not necessarily of equal diameter. This knot is tied starting with ...

Overhand Loop
The overhand loop is a simple knot which forms a fixed loop in a rope. Made by tying an overhand knot in the bight, it can be tied anywhere along a rope (does not need any working end). The knot can be used for attaching clips, hooks, other rope, etc., but has the disadvantage that it is likely to jam tight when the rope has been pulled and the knot may need to be cut off. It also has some uses in kite-flying, though other knots may be better. It is commonly disapproved by cadets because of its tendency to be misused as an alternative to the bowline 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 refe ....

Alpine Butterfly Knot
The butterfly loop, also known as lineman's loop, butterfly knot, alpine butterfly knot and lineman's rider, is a knot used to form a fixed loop in the middle of a rope. Tied in the bight, it can be made in a rope without access to either of the ends; this is a distinct advantage when working with long climbing ropes. The butterfly loop is an excellent mid-line rigging knot; it handles multi-directional loading well and has a symmetrical shape that makes it easy to inspect. In a climbing context it is also useful for traverse lines, some anchors, shortening rope slings, and for isolating damaged sections of rope. History The earliest known presentation of the knot was in A.A. Burger's 1914 work ''Rope and Its Uses'', included in an agricultural extension bulletin from what is now Iowa State University. Burger called the knot a lineman's rider stating it was often used by "linemen and especially telephone men". The knot's security and ability to withstand tension in any dir ...

Marlinespike Hitch
The marlinespike hitch is a temporary knot used to attach a rod to a rope in order to form a handle.Clifford W. Ashley, ''The Ashley Book of Knots'' (New York: Doubleday, 1944), 330. 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. As the name suggests, the type of rod traditionally used with this hitch is a marlinespike. The advantages of this hitch over others which might serve the purpose are its quickness of tying and ease of releasing. Topologically it is a form of the noose, but in practice this hitch is not allowed to collapse into that shape. When it does capsize into a traditional noose, it can jam against the rod, making it much more difficult to release.Ashley, 303, 305. The hitch is frequently used by hammock campers to attach adjustable rope slings ("whoopie slings") to the webbing straps that are used to attach hammocks to trees. By p ...

Slipped Buntline Hitch
The buntline hitch is a knot used for attaching a rope to an object. It is formed by passing the working end around an object, then making a clove hitch around the rope's standing part and taking care that the turns of the clove hitch progress ''towards'' the object rather than away from it. Secure and easily tied, the buntline hitch will jam when subjected to extreme loads. Given the knot's propensity to jam, it is often made in slipped form. History Simple and effective, the buntline hitch dates to the age of sail, when it was used to secure buntlines to the foot of the sailsBrion Toss, ''Chapman's Nautical Guides: Knots'' (New York: Hearst Marine Books, 1990), 39.Clifford W. Ashley, ''The Ashley Book of Knots'' (New York: Doubleday, 1944), 310. on square-rigged ships.

Sheet Bend
The sheet bend (also known as weaver's knot and weaver's hitch) is a bend knot. It is practical for joining lines of different diameter or rigidity. It is quick and easy to tie, and is considered so essential it is the first knot given in the '' Ashley Book of Knots''. Additionally, it is one of the six knots given in the International Guild of Knot Tyers' Six Knot Challenge, along with the clove hitch, bowline, reef knot (square knot), round turn and two half-hitches, and sheepshank. The sheet bend is related in structure to the bowline; like the bowline, it has a tendency to work loose when not under load. For increased security, it is sometimes recommended that one add another turn in the smaller end, making a double sheet bend; in most cases, however, a single sheet bend should suffice. The becket hitch is another structurally similar knot. As a bend, its advantages lie in its simplicity and non-jamming properties. It is commonly taught in Scouting. Definition A ...

Half Hitch
The half hitch is a simple List of hitch knots, hitch knot, where the Knot#Working end, working end of a line is brought over and under the Knot#Standing part, standing part. Insecure on its own, it is a valuable component of a wide variety of useful and reliable List of hitch knots, hitches, Bend knot, bends, and knots. Securing an additional single hitch to the rope's standing part produces the related knot two half-hitches.Alternatively, a half hitch may be made secure on its own by placing the final crossing opposite to the turn around the working end. This locks the end in place, and holds fast as long as the hitch is loaded by a steady pull. A half hitch in this configuration is sometimes used to tie strings to the bridge of a classical guitar. Another instance where a half hitch stands on its own without additional embellishment is when added to a timber hitch to help stabilize a load in the direction of pull. A timber hitch is tied on the far end of the load to bind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. 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. 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 climbing to tie into two anchor bolts independently. This knot is convenient when a dependable loop is required but neither end of the ...

Bowline
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 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 by s ...
