Double Overhand Knot
The double overhand knot or barrel knot is simply an extension of the regular overhand knot, made with one additional pass. The result is slightly larger and more difficult to untie. It forms the first part of the surgeon's knot and both sides of a double fisherman's knot. According to ''The Ashley Book of Knots'', "A double overhand knot tied in a cat-o'-nine-tails is termed a blood knot." When weighted, it can be difficult to untie, especially when wet. The strangle knot is a rearranged double overhand knot made around an object. It is sometimes used to secure items to posts. Instructions for tying # Tie an overhand knot at the end of a rope but do not tighten the knot down. # Pass the end of the line through the loop created by the first overhand knot. # Tighten the knot down while sliding it into place at the end of the line. Be sure to leave some tail sticking out from the end of the knot. Alternatively, the working end of the rope can be wrapped around the standing ...

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.

Surgeon's Knot
The surgeon's knot is a surgical knot and is a simple modification to the reef knot. It adds an extra twist when tying the first throw, forming a double overhand knot. The additional turn provides more friction and can reduce loosening while the second half of the knot is tied. This knot is commonly used by surgeons in situations where it is important to maintain tension on a suture, giving it its name. Surgeon's knots are also used in fly fishing, in tying quilts, and for tying knots with twine; it is particularly useful in tying raw meat with butcher's twine, as the wet meat creates similar risks of loosening as surgery. Some sources categorize the surgeon's knot as a bend, since it can be effective as such. Like the reef knot, the surgeon's knot capsizes and fails if one of the working ends is pulled away from the standing end closest to it.

Strangle Knot
The strangle knot is a simple binding knot. Similar to the constrictor knot, it also features an overhand knot under a riding turn. A visible difference is that the ends emerge at the outside edges, rather than between the turns as for a constrictor. This knot is a rearranged double overhand knot and makes up each half of the double fisherman's knot. See also *List of binding knots *List of knots *Clove hitch The clove hitch is a type of knot. Along with the bowline and the sheet bend, it is often considered one of the most important knots. A clove hitch is two successive half-hitches around an object.

Double Fisherman's Knot
The double fisherman's knot or grapevine knot is a bend. This knot and the triple fisherman's knot are the variations used most often in climbing, arboriculture, and search and rescue. The knot is formed by tying a double overhand knot, in its strangle knot form, with each end around the opposite line's standing part. Usage A primary use of this knot is to form high strength (round) slings of cord for connecting pieces of a climber's protection system. Other uses This knot, along with the basic fisherman's knot can be used to join the ends of a necklace cord. The two strangle knots are left separated, and in this way the length of the necklace can be adjusted without breaking or untying the strand.

Cinquefoil Knot
In knot theory, the cinquefoil knot, also known as Solomon's seal knot or the pentafoil knot, is one of two knots with crossing number five, the other being the three-twist knot. It is listed as the 51 knot in the Alexander-Briggs notation, and can also be described as the (5,2)-torus knot. The cinquefoil is the closed version of the double overhand knot. Properties The cinquefoil is a prime knot. Its writhe is 5, and it is invertible but not amphichiral. Its Alexander polynomial is :\Delta(t) = t^2 - t + 1 - t^ + t^, its Conway polynomial is :\nabla(z) = z^4 + 3z^2 + 1, and its Jones polynomial is :V(q) = q^ + q^ - q^ + q^ - q^. These are the same as the Alexander, Conway, and Jones polynomials of the knot 10132. However, the Kauffman polynomial can be used to distinguish between these two knots. History The name “cinquefoil” comes from the five-petaled flowers of plants in the genus ''Potentilla''. See also * Pentagram * Trefoil knot * 7₁ knot * Skein relation ...

The Ashley Book Of Knots
''The Ashley Book of Knots'' is an encyclopedia of knots written and illustrated by the American sailor and artist Clifford W. Ashley. First published in 1944, it was the culmination of over 11 years of work. The book contains 3,857 numbered entries (the final number, "3854", is added to by three "1/2" #s (794.5, 1034.5, & 2585.5) and, in later editions of the book, #1425a for Hunter's Bend; and one number has no entry) and approximately 7,000 illustrations. The entries include knot instructions, uses, and some histories, categorized by type or function. It remains one of the most important and comprehensive books on knots. Use as a reference Due to its scope and wide availability, ''The Ashley Book of Knots'' has become a significant reference work in the field of knotting. The numbers Ashley assigned to each knot can be used to unambiguously identify them. This helps to identify knots despite local colloquialisms or identification changes.

Cat-o'-nine-tails
The cat o' nine tails, commonly shortened to the cat, is a type of multi-tailed whip or flail that originated as an implement for severe physical punishment, notably in the Royal Navy and British Army, and as a judicial punishment in Britain and some other countries. Etymology The term first appears in 1681 in reports of a London murder. The term came into wider circulation in 1695 after its mention by a character in William Congreve's play ''Love for Love'', although the design is much older. It was probably so called in reference to its "claws", which inflict parallel wounds. There are equivalent terms in many languages, usually strictly translating, and also some analogous terms referring to a similar instrument's number of tails (cord or leather), such as the Dutch ''zevenstaart'' (seven tail , ''negenstaart'' (nine tail , the Spanish ''gato de nueve colas'' or the Italian ''gatto a nove code''.
