A binding knot is a knot

Knot

A knot is a method of fastening or securing linear material such as rope by tying or interweaving. It may consist of a length of one or several segments of rope, string, webbing, twine, strap, or even chain interwoven such that the line can bind to itself or to some other object—the "load"...

 that may be used to keep an object or multiple loose objects together, using a string or a rope that passes at least once around them. There are various binding knots, divided into two types. Friction knots are held in place by the friction

Friction

Friction is the force resisting the relative motion of solid surfaces, fluid layers, and/or material elements sliding against each other. There are several types of friction:...

 between the windings of line. Knotted-ends knots are held in place by the two ends of the line being knotted together.

Whipping

Whipping knot

A whipping knot or whipping is a binding of twine around the end of a rope to prevent the fibres of the rope from unravelling.When a rope is cut, there is a natural tendency for the cut end to fray. A whipping is one way to try to prevent this, by applying multiple turns of twine tightly around...

 and seizing

Seizing

Seizings are a class of knots used to semi-permanently bind together two ropes, two parts of the same rope, or rope and another object. Akin to lashings, they use string or small-stuff to produce friction and leverage to immobilize larger ropes. Seizings are not recommended for heavy loads....

 serve a similar function to binding knots, but are classified differently since they contain many turns, like a lashing.

This is a list of binding knots.

• Boa knot
  Boa knot
  The boa knot is a modern, binding knot invented by weaver Peter Collingwood in 1996. His intention was to develop a knot that would hold well when the constricted object was cut close to the winds of the knot....

• Constrictor knot
  Constrictor knot
  The constrictor knot is one of the most effective binding knots. Simple and secure, it is a harsh knot that can be difficult or impossible to untie once tightened. It is made similarly to a clove hitch but with one end passed under the other, forming an overhand knot under a riding turn...
  
  
• Corned beef knot
  Corned beef knot
  The corned beef knot is a binding knot usually made in small line or string. It gains its name by often being used for binding the meat of the same name while it is being cooked. Since corned beef shrinks during cooking, the knot needs to be tightened several times during the process.-Tying:A...
  
  
• Granny knot
  Granny knot
  The granny knot is a binding knot, used to secure a rope or line around an object. It is considered inferior to the reef knot, which it superficially resembles. Neither of these knots should be used as a bend for attaching two ropes together....
  
  
• Grief knot
  Grief knot
  A grief knot is a knot which combines the features of a granny knot and a thief knot, producing a result which is not generally useful for working purposes. Its name is an example of a portmanteau, from granny and thief.The grief knot resembles the granny knot, but tied in trans form as opposed...
  
  
• Ground-line hitch
  Ground-line hitch
  The ground-line hitch is a type of knot used to attach a rope to an object. Worked-up and dressed properly, it is more secure than the simpler clove hitch and has less tendency to jam, but does not respond well to swinging. It can also be used as a simple binding knot and is classed among several...
  
  
• Miller's knot
  Miller's knot
  A miller's knot is a binding knot used to secure the opening of a sack or bag. Historically, large sacks often contained grains; thus the association of these knots with the miller's trade...
  
  
• Packer's knot
  Packer's knot
  The packer's knot is a binding knot which is easily pulled taut and quickly locked in position. It is most often made in small line or string, such as that used for hand baling, parcel tying, and binding roasts. This latter use, and its general form, make it a member of a class of similar knots...
  
  
• Reef knot
  Reef knot
  The reef knot or square knot is an ancient and simple binding knot used to secure a rope or line around an object. Although the reef knot is often seen used for tying two ropes together, it is not recommended for this purpose due to potential instability of the knot.A reef knot is formed by tying...
  
  
• Strangle knot
  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. The difference is that the ends emerge at the outside edges, rather than between the turns as for a constrictor. This knot is actually a rearranged double overhand...
  
  
• Surgeon's knot
  Surgeon's knot
  The surgeon's knot is a simple modification to the reef knot. It adds an extra twist when tying the first throw, forming a double overhand knot, thus adding friction which makes the knot more secure. This knot is commonly used by surgeons in situations where it is important to maintain tension on...
  
  
• Thief knot
  Thief knot
  The Thief knot resembles the reef knot except that the free, or working, ends are on opposite sides.

If another sailor went through the bag, the odds were high the thief would...
  
  
• Jamming knot
  Jamming 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...
