Offset Overhand Bend
The offset overhand bend (OOB, ABoK No. 1410) is a conceptually simple and easy to tie 'end-to-end joining knot' (ie bend). It is formed by holding two rope ends next to each other and tying an overhand knot in them as if they were a single line. Due to its common use in several fields, this bend has become known by many names, such as thumb knot, openhand knot, one-sided overhand knot or flat overhand bend (FOB), though the terms "one-sided" and "flat" are considered incorrect. Geometry The term 'offset' refers to the knot core being displaced from the axis of tension. This geometry allows the knot to more easily translate around an edge - particularly a 90 degree edge. Uses Long used by weavers to join the ends of yarn, the offset water knot is very old. It was one of the knots likely identified among the possessions of Ötzi the Iceman, who dates from 3300 BC. The knot is also tied in a slipped form by mechanical balers to bind straw and hay, but this bend is not prac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overhand Knot
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 Tying There are a number of ways to tie the Overhand knot. * Thumb method – create a loop and push the working end through the loop with your thumb. * Overhand method – create a bight, by twisting the hand over at the wrist and sticking your hand in the hole, pinch the working end with your fingers and pull through the loop.

3300 BC
The 33rd century BC was a century that lasted from the year 3300 BC to 3201 BC. It is impossible to precisely date events that happened around the time of this millennium and all dates mentioned here are estimates mostly based on geological and anthropological analysis. The bronze age started in the 33rd century BC. Events * Major climate shift possibly due to shift in solar activity. Glaciers expand, covering plants. Atmospheric temperatures fall. * Sahara changes from a habitable region into a barren desert * Ancient Egypt begins using clay, bone and ivory tags to label boxes, possibly an example of proto-writing * Indus Valley civilisation (also known as Harappan civilization) begins in Harappa *c. 3300 BC: Archaeological evidence suggests the transition from Copper to Bronze took place around 3300 BC. *c. 3300 BC: Harappan script is developed in Indus Valley *c. 3300 BC: Pictographs in Uruk * 3300 BC: to 3000 BC: Face of a woman, from Uruk (modern Warka, Iraq) is made.

List Of Knots
This list of knots includes many alternative names for common knots and lashings. Knot names have evolved over time, and there are many conflicting or confusing naming issues. The overhand knot, for example, is also known as the thumb knot. The figure-eight knot is also known as the Savoy knot or the Flemish knot. A * Adjustable Bend – can be easily lengthened or shortened * Adjustable Grip Hitch – a simple hitch which may easily be shifted up and down the rope while slack *Albright Special – used to tie two different diameters of line together, for instance to tie monofilament to braid *Alpine Butterfly (also known as Butterfly Loop) – a static loop mostly used by mountain climbers and rappellers for securing a carabiner to static rope. * Alternate Ring Hitching – covering a ring in hitching can prevent damage * Anchor Bend – attaching a rope to a ring or similar termination *Angler's Loop – knot which forms a fixed loop.

Dressing (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 ...

Figure-eight Knot
The figure-eight knot or figure-of-eight knot is a type of stopper knot. It is very important in both sailing and rock climbing 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 the figure-eight knot with two half twists added before the end is finally stuck. 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 " splice" together two ropes, not necessarily of equal diameter. This knot is tied starting with a loose figure-eight knot on one rope ...

Offset Figure-eight Bend
The offset figure-eight bend is a poor knot that has been implicated in the deaths of several rock climbers. The knot may capsize (invert) under load, as shown in the figure, and this can happen repeatedly. Each inversion reduces the lengths of the tails. Once the tails are used up completely, the knot comes undone. More secure knots for this purpose are the Flemish bend (the "figure eight bend"), (doubled) offset overhand bend, or double fisherman's knot.

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 in t ...

Baler
A baler or hay baler is a piece of farm machinery used to compress a cut and raked crop (such as hay, cotton, flax straw, salt marsh hay, or silage) into compact bales that are easy to handle, transport, and store. Often, bales are configured to dry and preserve some intrinsic (e.g. the nutritional) value of the plants bundled. Different types of balers are commonly used, each producing a different type of balerectangular or cylindrical, of various sizes, bound with twine, strapping, netting, or wire. Industrial balers are also used in material recycling facilities, primarily for baling metal, plastic, or paper for transport. History Before the 19th century, hay was cut by hand and most typically stored in haystacks using hay forks to rake and gather the scythed grasses into optimal sized heapsneither too large, promoting conditions favourable for spontaneous combustion, nor too small, which would mean much of the pile is susceptible to rotting. These haystacks lifted most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ötzi The Iceman
Ötzi, also called the Iceman, is the natural mummy of a man who lived some time between 3350 and 3105 BC, discovered in September 1991 in the Ötztal Alps (hence the nickname "Ötzi") on the border between Austria and Italy. Ötzi is believed to have been murdered, due to the discovery of an arrowhead embedded in his left shoulder and various other wounds. The nature of his life and the circumstances of his death are the subject of much investigation and speculation. He is Europe's oldest known natural human mummy, offering an unprecedented view of Chalcolithic (Copper Age) Europeans. His body and belongings are displayed in the South Tyrol Museum of Archaeology in Bolzano, South Tyrol, Italy. Discovery Ötzi was found on 19 September 1991 by two German tourists, at an elevation of on the east ridge of the Fineilspitze in the Ötztal Alps on the Austrian–Italian border, near Similaun mountain and the Tisenjoch pass.

Water Knot
The water knot (also tape knot, ring bend, grass knot, or overhand follow-through) is a knot frequently used in climbing for joining two ends of webbing together, for instance when making a sling. Tying It is tied by forming an overhand knot in one end and then following it with the other end, feeding in the opposite direction. The ends should be left at least long and the knot should be "set" by tightening it with full body weight. The ends can be knotted, taped or lightly sewn to the standing parts to help prevent them from creeping back into the knot.Craig Luebben, ''Knots for Climbers'' (Evergreen, Colorado: Chockstone Press, 1993), 19. Uses The knot can be used for joining flat materials such as leather or tape.John 'Lofty' Wiseman SAS ''Survival Handbook, Revised Edition''; William Morrow Paperbacks (2009) Security Once tied, for additional security each end should be tied in a double overhand stopper knot around the other standing end.
