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.
Tatting is a technique for handcrafting a particularly durable lace from a series of knots and loops. Tatting can be used to make lace edging as well as doilies, collars, accessories such as earrings, necklaces, waist beads, and other decorative pieces. The lace is formed by a pattern of rings and chains formed from a series of cow hitch or half-hitch knots, called double stitches, over a core thread. Gaps can be left between the stitches to form picots, which are used for practical construction as well as decorative effect.
Celtic knots are a variety of knots and stylized graphical representations of knots used for decoration, used extensively in the Celtic style of Insular art. These knots are most known for their adaptation for use in the ornamentation of Christian monuments and manuscripts, such as the 8th-century St. Teilo Gospels, the Book of Kells and the Lindisfarne Gospels. Most are endless knots, and many are varieties of basket weave knots.
An angler's loop, otherwise known as a perfection loop, is a type of knot which forms a fixed loop. Useful for fine or slippery line, it is one of the few loop knots which holds well in bungee cord. It is quite secure, but it jams badly and is not suitable if the knot will need to be untied.
A zeppelin bend is an end-to-end joining knot formed by two symmetrically interlinked overhand knots. It is stable, secure, and highly resistant to jamming. It is also resistant to the effects of slack shaking and cyclic loading.
A double bowline is a type of loop knot. Instead of the single turn of the regular bowline, the double bowline uses a round turn. This forms a more secure loop than a standard bowline.
Chinese knotting, also known as zhongguo jie, is a Chinese folk art with ties to Buddhism and Taoism. A Chinese knot is made from a single length of cord that is woven into different shapes, with each shape having a symbolic meaning. The most common color used in Chinese knotting is red, a color associated with luck in Chinese culture, although any color can be used. Charms, beads, and jade are sometimes incorporated into a Chinese knot. It is believed that Chinese knotting originated for recording information and exchanging messages before writing was commonplace. Traditionally, Chinese knots acted as good-luck charms to ward off evil spirits. Chinese knots are used today to decorate homes during festivities and are also commonly seen in traditional jade jewellery and traditional Chinese clothing.
Macramé is a form of textile produced using knotting techniques.
The sheet bend is a bend knot. It is practical for joining lines of different diameter or rigidity.
A stopper knot is a knot that creates a fixed thicker point on an otherwise-uniform thickness rope for the purpose of preventing the rope, at that point, from slipping through a narrow passage, such as a hole in a block. To pass a rope through a block, or hole, is to reeve it. To pull it out is to unreeve it. Stopper knots prevent the rope from unreeving on its own.
A wall and crown knot is a decorative kind of rope button. The original use of the knot was to put at the end of the ropes on either side of a gangway leading onto a ship as stoppers.
A Turk's head knot, sometimes known as a sailor's knot, is a decorative knot with a variable number of interwoven strands forming a closed loop. The name refers to a general family of knots, not an individual knot. While this knot is typically made around a cylinder, it can also be formed into a flat, mat-like shape. Some variants can be arranged into a roughly spherical shape, akin to a monkey's fist knot.
The half hitch is a simple hitch knot, where the working end of a line is brought over and under the standing part. Insecure on its own, it is a valuable component of a wide variety of useful and reliable hitches, bends, and knots.
The half hitch is tied with one end of a rope which is passed around an object and secured to its own standing part with a single hitch.
The triple bowline knot is a variation of the bowline knot. The knot can be applied in emergency situations, such as mountain rescue.
Korean knots, also known as maedeup (매듭), is a traditional Korean handicraft which dates back to the Three Kingdom periods and have been influenced by Chinese knots.
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."
A friendship bracelet is a decorative bracelet given by one person to another as a symbol of friendship. Friendship bracelets are often handmade, usually of embroidery floss or thread and are a type of macramé. There are various styles and patterns, but most are based on the same simple half-hitch knot. They represent a friendship that is strong and everlasting.
Hemp jewelry uses hemp twine material which is made from the Cannabis sativa plant, otherwise known as “Common Hemp”, which is cultivated to make goods such as food, fuel, clothing and textiles, cosmetics, paints, paper, building materials, and plastics, among others. Some types of hemp jewelry include bracelets, necklaces, anklets, rings, watches, masks, purses, and other adornments. The jewelry can also make use of other materials, such as glass, wood, bones, rocks, or gems.
