Tom Fool's Knot
The Tom fool's knot, also known as the conjurer's knot, bow knot and Greek fool's knot, is a type of knot sometimes considered a handcuff knot, though usually considered somewhat inferior to it. It is a good knot with which to commence a slightly fancy sheepshank. It is also used as a trick knot due to the speed with which it can be made. The knot has a number of mainly decorative but also functional uses, such as sailing, boating, camping and restraining people. History Tom fool's knot is believed to be the knot ''"epankylotos brokhos"'' described by the 1st century AD Greek physician Heraklas. Tying It is formed by making two loops, not exactly overlaying each other. The inner half of each hitch or loop is pulled under and through the outer side of the opposite loop.

Handcuff Knot
A handcuff knot is a knot tied in the bight having two adjustable loops in opposing directions, able to be tightened around hands or feet. The knot itself does not possess any inherent locking action, and thus is not as easy to use for such purposes as the name might suggest. The knot is also known as a ''hobble knot'' for similar reasons, from the idea that the knot was sometimes used on the legs of horses to limit the distance their riders had to walk in the morning to retrieve them.

Sheepshank
A shank is a type of knot that is used to shorten a rope or take up slack, such as the sheepshank. The sheepshank knot is not stable. It will fall apart under too much load or too little load. The knot has several features which allow a rope to be shortened: * It provides two loops, one at each end of the knot which can be used to pass another rope through * The knot remains somewhat secure under tension; the coarser the rope the more secure it is (see Disadvantages, below) * The knot falls apart easily when tension is removed Construction methods A sheepshank knot may be constructed as follows: ... * Pull a section of rope back and lay it alongside the rope, so that the rope forms a Z approximately 20 cm long. * Flatten the Z so that there are 3 sections of rope lying alongside each other, with two U-bends where the rope reverses direction. * At each U-bend, grasp the U-bend in one hand, thus holding two of the rope sections. With the other hand form a small loop in the r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fireman's Chair Knot
A fireman's chair knot (also known as the chair knot, Man-O-War sheepshank, double fool's harness or the Shaw special) is a knot tied in the bight forming two adjustable, lockable loops. The knot consists of a handcuff knot finished with a locking half hitch around each loop. The loops remain adjustable until the half hitches are tightened. Usage The knot was first introduced by the Victorian chief fire officer Eyre Massey-Shaw in 1876 on a windy afternoon while slightly inebriation, inebriated. Made with suitable rope by qualified personnel this knot can be used as a rescue Climbing harness, harness capable of supporting a person while being hoisted or lowered to safety. One loop supports the body, around the chest and under the arms, and the other loop supports the legs, under the knees. Tied towards the middle of a line, one end is used for lowering and the other end can serve as a tagline, to control the victim's position with respect to hazards during the descent. A sn ...

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 ...

Sailing
Sailing employs the wind—acting on sails, wingsails or kites—to propel a craft on the surface of the ''water'' (sailing ship, sailboat, raft, windsurfer, or kitesurfer), on ''ice'' (iceboat) or on ''land'' (land yacht) over a chosen course, which is often part of a larger plan of navigation. From prehistory until the second half of the 19th century, sailing craft were the primary means of maritime trade and transportation; exploration across the seas and oceans was reliant on sail for anything other than the shortest distances. Naval power in this period used sail to varying degrees depending on the current technology, culminating in the gun-armed sailing warships of the Age of Sail. Sail was slowly replaced by steam as the method of propulsion for ships over the latter part of the 19th century – seeing a gradual improvement in the technology of steam through a number of stepwise developments. Steam allowed scheduled services that ran at higher average speeds than sail ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boating
Boating is the leisurely activity of travelling by boat, or the recreational use of a boat whether Motorboat, powerboats, Sailing, sailboats, or man-powered vessels (such as rowing and paddle boats), focused on the travel itself, as well as sports activities, such as fishing or waterskiing. It is a popular activity, and there are millions of boaters worldwide. Types of boats Boats (boat types) can be categorized into 3 different types types of board categories, unpowered, motor boats, and sailboats.Recreational boats (sometimes called pleasure craft, especially for less sporting activities) fall into several broad categories, and additional subcategories. Broad categories include Dinghy, dinghies (generally under 16 feet (5 m) powered by sail, small engines, or muscle power) usually made from hardwood or inflatable rubber. paddle sports boats (Kayak, kayaks, rowing shells, Canoe, canoes), runabouts (15–25 ft. (5–8 m) powerboats with either outboard, sterndrive, or inboard ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camping
Camping is an outdoor activity involving overnight stays away from home, either without shelter or using basic shelter such as a tent, or a recreational vehicle. Typically, participants leave developed areas to spend time outdoors in more natural ones in pursuit of activities providing them enjoyment or an educational experience. The night (or more) spent outdoors distinguishes camping from day-tripping, picnicking, and other similarly short-term recreational activities. Camping as a recreational activity became popular among elites in the early 20th century. With time, it grew in popularity among other socioeconomic classes. Modern campers frequent publicly owned natural resources such as national and state parks, wilderness areas, and commercial campgrounds. In a few countries, such as Sweden and Scotland, public camping is legal on privately held land as well. Camping is a key part of many youth organizations around the world, such as Scouting, which use it to teach bot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Physical Restraint
Physical restraint refers to means of purposely limiting or obstructing the freedom of a person's bodily movement. Basic methods Usually, binding objects such as handcuffs, legcuffs, ropes, chains, straps or straitjackets are used for this purpose. Alternatively different kinds of arm locks deriving from unarmed combat methods or martial arts are frequently used to restrain a person, which are predominantly used by trained police or correctional officers. This less commonly also extends to joint locks and pinning techniques. The freedom of movement in terms of locomotion is usually limited, by locking a person into an enclosed space, such as a prison cell and by chaining or binding someone to a heavy or immobile object. This effect can also be achieved by seizing and withholding specific items of clothing, that are normally used for protection against common adversities of the environment. Examples can be protective clothing against temperature, forcing the individual to re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heraklas
Heraklas ( grc-gre, Ἡρακλᾶς) was a Greek physician of the 1st century AD whose descriptions of surgeons' knots and slings are preserved in book 48 of Oribasius' ''Medical Collections'' (Ἰατρικαὶ Συναγωγαί, ''Iatrikai Synagogai'') under the title ''From Heraklas''. Describing them in detail, Heraklas discussed 16 different knots and slings, including the earliest known written account of a string figure. Accompanying illustrations of the knots were added later by Renaissance copyists, but modern analysis of the writings by knot experts has shown many of these early drawings to contain significant errors or misinterpretations. The knots identified The current understanding of Heraklas' knots results primarily from analysis and identification by Hjalmar Öhrvall, Lawrence G. Miller, and Cyrus L. Day, although slightly differing interpretations and refinements continue to be made. The table below shows the knots believed to have been described by Her ...
