Chain Sinnet
A chain sinnet (or chain sennit) is a method of shortening a rope or other Wire rope, cable while in use or for storage. It is formed by making a series of simple crochet-like stitches in the line.Clifford W. Ashley, ''The Ashley Book of Knots'' (New York: Doubleday, 1944), 209. It can also reduce tangling while a rope is being washed in a washing machine. Tying To tie: #Create a loop in the rope. Then pull a Bight (knot), bight of the working part through the loop, creating an overhand noose knot. #Pull another bight of the working part through the loop of the previous stitch. #Tighten the stitch to the desired degree by pulling on both sides of the loop. Adjust the loop by pulling on the working end to keep it a reasonable size. #Repeat steps 2–3 until the rope has been sufficiently shortened. #To lock the sinnet, pass the working end through the final loop. To restore the rope to its original length, pull the end passed in the last step back through the final loop and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rope
A rope is a group of yarns, Plying, plies, fibres, or strands that are plying, twisted or braided together into a larger and stronger form. Ropes have high tensile strength and can be used for dragging and lifting. Rope is thicker and stronger than similarly constructed cord, String (structure), string, and twine. Construction Rope may be constructed of any long, stringy, fibrous material (e.g., rattan, a natural material), but generally is constructed of certain natural fibre, natural or synthetic fibre, synthetic fibres. Synthetic fibre ropes are significantly stronger than their natural fibre counterparts, they have a higher tensile strength, they are more resistant to rotting than ropes created from natural fibres, and they can be made to float on water. But synthetic ropes also possess certain disadvantages, including slipperiness, and some can be damaged more easily by UV light. Common natural fibres for rope are Manila hemp, hemp, linen, cotton, coir, jute, straw, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wire Rope
Steel wire rope (right hand lang lay) Wire rope is composed of as few as two solid, metal wires twisted into a helix that forms a composite ''rope'', in a pattern known as ''laid rope''. Larger diameter wire rope consists of multiple strands of such laid rope in a pattern known as ''cable laid''. Manufactured using an industrial machine known as a strander, the wires are fed through a series of barrels and spun into their final composite orientation. In stricter senses, the term ''wire rope'' refers to a diameter larger than , with smaller gauges designated cable or cords. Initially wrought iron wires were used, but today steel is the main material used for wire ropes. Historically, wire rope evolved from wrought iron chains, which had a record of mechanical failure. While flaws in chain links or solid steel bars can lead to catastrophic failure A catastrophic failure is a sudden and total failure from which recovery is impossible. Catastrophic failures often lead to cascadi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crochet
Crochet (; ) is a process of creating textiles by using a crochet hook to interlock loops of yarn, thread (yarn), thread, or strands of other materials. The name is derived from the French term ''crochet'', which means 'hook'. Hooks can be made from different materials (aluminum, steel, metal, wood, bamboo, bone, etc.), sizes, and types (in-line, tapered, ergonomic, etc.). The key difference between crochet and knitting, beyond the implements used for their production, is that each stitch in crochet is completed before the next one, while knitting keeps many stitches open at a time. Some variant forms of crochet, such as Tunisian crochet and Broomstick lace, do keep multiple crochet stitches open at a time. Etymology The word crochet is derived from the French language, French word , a diminutive of ''croche'', in turn from the Germanic languages, Germanic ''croc'', both meaning "hook". It was used in 17th-century French lace-making, where the term ''Crochetage'' designated a sti ... [...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."

Overhand Noose
The double overhand noose is a very secure hitch knot. It might be used by cavers and canyoneers to bind a cow tail or a foot loop to a carabiner.

The bound object has to be removed before untying. As the double overhand knot, it neither slips nor turns around. However, a third round turn might be useful with some highly lubricious spectra/nylon ropes.

Chain Stitch
Chain stitch is a sewing and embroidery technique in which a series of looped stitches form a chain-like pattern. Chain stitch is an ancient craft – examples of surviving Chinese chain stitch embroidery worked in silk thread have been dated to the Warring States period (5th – 3rd century BC). Handmade chain stitch embroidery does not require that the needle pass through more than one layer of fabric. For this reason the stitch is an effective surface embellishment near seams on finished fabric. Because chain stitches can form flowing, curved lines, they are used in many surface embroidery styles that mimic "drawing" in thread. Chain stitches are also used in making tambour lace, needlelace, macramé and crochet. In Azerbaijan, in the Sheki region, this ancient type of needlework is called ''tekeldus''. History The earliest archaeological evidence of chain stitch embroidery dates from 1100 BC in China. Excavated from royal tombs, the embroidery was made using thr ...

Coil Knot
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. Mountaineer's coil The mountaineer's coil (also alpine coil, climber's coil, lap coil, or standing coil) is a traditional method used by climbers to store and transport a climbing rope. This older style coil is noted as being more prone to twists and tangles than the butterfly coil, and care must be taken upon uncoiling to avoid these problems. Tying method Begin by taking hold of the rope in one hand with its end facing you. Coil the rope in arm's length sections with your free hand (extending it away from the other as far as it will reach to ensure each segment is of equal length as it is gathered). Alternate tucking the new gather in front and behind the previous coil to avoid putting a half-turn in the rope with each coil. When the last segment is reached form a short bight atop the gathered rope with i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daisy Chain (climbing)
Rock-climbing equipment varies with the specific type of climbing that is undertaken. Bouldering needs the least equipment outside of climbing shoes, climbing chalk and optional crash pads. Sport climbing adds ropes, harnesses, belay devices, and quickdraws to clip into pre-drilled bolts. Traditional climbing adds the need to carry a "rack" of temporary passive and active protection devices. Multi-pitch climbing, and the related big wall climbing, adds devices to assist in ascending and descending fixed ropes. Finally, aid climbing uses unique equipment to give mechanical assistance to the climber in their upward movement (e.g. aiders). Advances in equipment are a key part of the rock climbing history, starting with the climbing rope. Modern devices enable climbers to perform tasks previously done manually, with greater control – in all conditions – and with less effort. Examples of replacements include the harness (replaced tying the rope around the waist), the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sennit
Sennit is a type of cordage made by plaiting rope fibres or strands of dried fibre or grass. In western European nautical traditions, it was used to make flat plaited straps for use aboard ship. It can be used ornamentally in crafts, like a kind of macramé, or to make straw hats. Sennit is an important material in the cultures of Oceania, where it is used in traditional architecture, boat building, fishing and as an ornamentation. Oceania Tonga Sennit in Tonga is called ''kafa.'' Fiji The Fijian term used is '' magimagi'', a craft product of the Fiji Islands. Hawai'i The term is also used in Hawaii and throughout Polynesia for cordage made by braiding the fibers of coconut husks. It was important in attaching the '' ama'' (outrigger float) via the '' iako'' (spars) to the hull of canoes, stones to war-club handles, erecting ''hale'' (houses), etc. Samoa In the Samoan language, sennit is called ''afa''. It was used as cordage in the construction of traditional Samoan ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sling (climbing Equipment)
A sling is an item of climbing equipment consisting of a tied or sewn loop of webbing. These can be wrapped around sections of rock, hitched to other pieces of equipment, or tied directly to a tensioned line using a Prusik style knot. They may be used as anchors, to extend an anchor to reduce rope drag, in anchor equalization, or to climb a rope. Uses In 1957 Jan and Herb Conn wrote an article titled "the versatile runner" with a long list of uses, which is still quite accurate: # Slings and now more often 3-foot alpine draws or shorter quickdraws are used in-between pieces of protection and the rope to minimize rope drag # Hitch around a chock stone or a tree to use as passive protectionConn, Jan and Herb (November 1957). ''The versatile runner'' - Summit (PDF) # Clove hitch around chicken heads or sling around horns # Longer slings or cordelettes can be used for equalized belay stations # Slings can be used as improvised "personal anchor system" attaching climber di ...
