<span class="mw-page-title-main">Knot</span> Method of fastening or securing linear material

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.

<span class="mw-page-title-main">Pulley</span> Wheel to support movement and change of direction of a taut cable

A pulley is a wheel on an axle or shaft that is designed to support movement and change of direction of a taut cable or belt, or transfer of power between the shaft and cable or belt. In the case of a pulley supported by a frame or shell that does not transfer power to a shaft, but is used to guide the cable or exert a force, the supporting shell is called a block, and the pulley may be called a sheave or pulley wheel.

<span class="mw-page-title-main">Sheepshank</span> Type of knot

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.

<span class="mw-page-title-main">Trucker's hitch</span> Type of knot

The trucker's hitch is a compound knot commonly used for securing loads on trucks or trailers. The general arrangement, using loops and turns in the rope itself to form a crude block and tackle, has long been used to tension lines and is known by multiple names. Knot author Geoffrey Budworth claims the knot can be traced back to the days when carters and hawkers used horse-drawn conveyances to move their wares from place to place.

<span class="mw-page-title-main">Timber hitch</span> Type of knot

The timber hitch is a knot used to attach a single length of rope to a cylindrical object. Secure while tension is maintained, it is easily untied even after heavy loading.

<span class="mw-page-title-main">Block and tackle</span> System of two or more pulleys and a rope or cable

A block and tackle or only tackle is a system of two or more pulleys with a rope or cable threaded between them, usually used to lift heavy loads.

<span class="mw-page-title-main">Fireman's chair knot</span> Type of knot

A fireman's chair knot 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.

<span class="mw-page-title-main">Highwayman's hitch</span> Quick-release draw loop knot

The Highwayman’s hitch is a quick-release draw hitch used for temporarily securing a load that will need to be released easily and cleanly. The hitch can be untied with a tug of the working end, even when under tension. The highwayman's hitch can be tied in the middle of a rope, and so the working end does not need to be passed around the anchor when tying or releasing.

<span class="mw-page-title-main">Stopper knot</span> Knot that forms a fixed thicker point to prevent unreeving

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.

<span class="mw-page-title-main">Munter hitch</span> Adjustable knot used control friction in a belay system

The Munter hitch, also known as the Italian hitch, mezzo barcaiolo or the crossing hitch, is a simple adjustable knot, commonly used by climbers, cavers, and rescuers to control friction in a life-lining or belay system. To climbers, this hitch is also known as HMS, the abbreviation for the German term Halbmastwurfsicherung, meaning half clove hitch belay. This technique can be used with a special "pear-shaped" HMS locking carabiner, or any locking carabiner wide enough to take two turns of the rope.

<span class="mw-page-title-main">Adjustable grip hitch</span> Type of friction hitch

The adjustable grip hitch is a simple and useful friction hitch which may easily be shifted up and down the rope while slack. It will hold fast when loaded, but slip when shock loaded until tension is relieved enough for it to again hold fast. It serves the same purpose as the taut-line hitch, e.g. tensioning a tent's guy line.

<span class="mw-page-title-main">Surgeon's knot</span> Type of 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.

<span class="mw-page-title-main">Bachmann knot</span> Type of knot

The Bachmann hitch is a friction hitch, named after the Austrian alpinist Franz Bachmann. It is useful when the friction hitch needs to be reset quickly or often or made to be self-tending as in crevasse and self-rescue.

<span class="mw-page-title-main">Prusik knot</span> Type of knot

A Prusik is a friction hitch or knot used to attach a loop of cord around a rope, applied in climbing, canyoneering, mountaineering, caving, rope rescue, ziplining, and by arborists. The term Prusik is a name for both the loops of cord used to tie the hitch and the hitch itself, and the verb is "to prusik". More casually, the term is used for any friction hitch or device that can grab a rope. Due to the pronunciation, the word is often misspelled Prussik, Prussick, or Prussic.

<span class="mw-page-title-main">Deadeye</span>

A deadeye is an item used in the standing and running rigging of traditional sailing ships. It is a smallish round thick wooden disc with one or more holes through it, perpendicular to the plane of the disc. Single and triple-hole deadeyes are most commonly seen. The three-holed blocks were called deadeyes because the position of the three holes resemble the eye and nose sockets of a sheep's skull.

In tennis, the strings are the part of a tennis racquet which make contact with the ball. The strings form a woven network inside the head of the racquet. Strings have been made with a variety of materials and possess varying properties that have been measured, such as dynamic stiffness, tension retention, thickness (gauge), string texture, and rebound efficiency.

<span class="mw-page-title-main">Farrimond friction hitch</span> Type of knot

The Farrimond friction hitch is a quick release adjustable friction hitch for use on lines under tension. It is useful when the length of a line will need to be periodically adjusted in order to maintain or adjust tension whilst remaining quick and easy to untie; such as when hanging the ridge line for a Basha. It can be used in very effective conjunction with the Siberian hitch for this purpose. It can also be used as a mooring knot.

<span class="mw-page-title-main">Jamming knot</span> Type of knot

As a type of binding knot, the jamming knot is good for constricting a bundle of objects such as sticks or brush. It is basically a taut-line hitch but the initial two wraps are on the outside of the working line rather than on the inside, and finished off with one wrap on the inside. Thus the knot holds tension towards the inside of the loop rather than the standing end of the rope as with the taut-line – turning a tension knot into a constricting knot. After the knot is tied, the knot is held with one hand, the standing end is pulled tight, and the knot should hold fast. This knot, as with the taut-line, can be difficult or impossible to tie on slick or particularly stiff rope.

<span class="mw-page-title-main">Tumble hitch</span>

The tumble hitch is a "slip-free", quick-release hitch knot used for temporarily securing a rope such that it can be released easily to be completely free of the hitched-to object. The hitch might be able to be untied with a tug of the working end, even when under tension; but the workings depend upon materials and forces; note that in some cases, "under tension" will amount to simply being tied and the line itself giving significant tension by weight. The tumble hitch is tied in the bight.
