The blackwall hitch is a temporary means of attaching a rope to a hook. Made of a simple half hitch over the hook, it will only hold when subjected to constant tension. It is used when the rope and hook are of equal size, but it is likely to slip if subjected to more than ordinary tension. Human life should never be trusted to it. [1]

Half hitch overhand knot

The half hitch is a simple overhand 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.

Knot method of fastening or securing linear material, such as rope, by tying or interweaving

A knot is an intentional complication in cordage which may be useful or decorative. Practical knots may be classified as hitches, bends, splices, or knots. A hitch fastens a rope to another object; a bend unites two rope ends; a splice is a multi-strand bend or loop. A knot in the strictest sense serves as 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.

Sheepshank 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.

Truckers hitch hitch knot

The trucker's hitch is a compound knot commonly used for securing loads on trucks or trailers. This 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.

Marlinespike hitch

The marlinespike hitch is a temporary knot used to attach a rod to a rope in order to form a handle. This allows more tension than could be produced comfortably by gripping the rope with the hands alone. It is useful when tightening knots and for other purposes in ropework.

Klemheist knot

The klemheist knot or French Machard knot is a type of friction hitch that grips the rope when weight is applied, and is free to move when the weight is released. It is used similarly to a Prusik knot or the Bachmann knot to ascend or descend a climbing rope. One advantage is that webbing can be used as an alternative to cord. The Klemheist is easier to slide up than a Prusik. The klemheist is also a way to attach a snubber to the anchor rope of small boats, with the advantage that it is easy to undo.

Highwaymans hitch quick-release draw loop knot

The draw hitch is a quick-release draw loop knot 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.

Cats paw (knot) hitch knot

The Cat's paw is a knot used for connecting a rope to an object. It is very similar to the cow hitch except there is an additional twist on each side of the bight, making it less prone to slipping.

The cat's-paw is the common hook hitch for slings. It is the same basic form as the bale sling hitch but has additional twists. Brady says "two or three altogether," and Steel, who mentioned the name in 1794, says "three twists." It is the best of all sling hitches and is often recommended for a slippery rope. But no hitch can slip when tied in a slings since it has no ends. All that is needed is a hitch that cannot jam, and this requirement the cat's-paw fills admirably. The knot spills instantly when removed from the hook. It is the hitch always used for heavy lifts.

Stopper knot knot that creates a fixed thicker point on an otherwise uniform thickness rope for the purpose of preventing unreeving

A stopper knot is a knot that creates a fixed thicker point on an otherwise-uniform thickness rope for the purpose of preventing unreeving: stopping the rope at that point from slipping out of a narrow passage. Stopper has three distinct meanings in the context of knotting and cordage. A decorative stopper knot may be referred to as a lanyard knot.

The single-strand stopper knot is...[one variety] of knob knots. Generally it is tied as a terminal knot in the end of a rope, where it forms a knob or bunch, the general purpose of which is to prevent unreeving. It is found in the ends of running rigging. It secures the end of a sewing thread; it provides a handhold or a foothold in bell ropes and footropes. It adds weight to the end of a heaving line, and it is often employed decoratively, but it should not be used to prevent unlaying and fraying except in small cord, twine, and the like, as a whipping is in every way preferable for large and valuable material.

Munter hitch

The Munter hitch, also known as the Italian hitch or the Crossing Hitch, is a simple knot, commonly used by climbers, cavers, and rescuers as part of a life-lining or belay system. To climbers, this knot 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. The Munter hitch is named after a Swiss mountain guide, Werner Munter, who popularised its use in mountaineering around 1970.

Buntline hitch hitch knot

The buntline hitch is a knot used for attaching a rope to an object. It is formed by passing the working end around an object, then making a clove hitch around the rope's standing part, taking care that the turns of the clove hitch progress towards the object rather than away from it. Secure and easily tied, the buntline hitch will jam when subjected to extreme loads. Given the knot's propensity to jam, it is often made in slipped form.

The buntline hitch, when bent to a yard, makes a more secure knot than two half hitches, but is more liable to jam. It differs from two half hitches in that the second half hitch is inside instead of outside the first one.

Adjustable grip 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.

Bachmann knot

The Bachmann hitch is a friction hitch. It is useful when the friction hitch needs to be reset quickly/often or made to be self-tending as in crevasse and self-rescue.

Becket hitch

A becket hitch, including the double becket or figure-of-eight becket hitch, is any hitch that is made on an eye loop, i.e. on a becket. A becket hitch has the same structure as the sheet bend, which joins, or "bends", the ends of two ropes together. The becket hitch, in contrast, fixes a rope to a closed eye or hook. In this instance, a becket means the eye or hook of a pulley block, an eye in the end of a rope, or a rope handle on a sailors sea chest.


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 and the hitch, and the verb is "to prusik". More casually, the term is used for any friction hitch or device that can grab a rope. The word is often misspelled as Prussik, Prussick or Prussic, as it is a homophone with the term prussic acid.

Halter hitch

The halter hitch is a type of knot used to connect a rope to an object. As the name implies, an animal's lead rope, attached to its halter, may be tied to a post or hitching rail with this knot. The benefit of the halter hitch is that it can be easily released by pulling on one end of the rope, even if it is under tension. Some sources show the knot being finished with the free end running through the slipped loop to prevent it from working loose or being untied by a clever animal, still allowing easy but not instant untying.

Falconers knot

The falconer's knot is a knot used in falconry to tether a bird of prey to a perch. Some sources show this knot to be identical to the halter hitch, but with a specific method of single-handed tying needed when the other hand is occupied holding the bird.

Farrimond friction hitch

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.

Diamond hitch

The diamond hitch is a lashing technique used mainly in the field of equine packing, to secure a set of objects, for instance a pair of pack-bags, pack-boxes or other gear onto a base, for instance a pack saddle frame, in which case it requires the use of a lash cinch. In the general sense it requires the base to be equipped with at least two points of anchorage, and a rope which is used to lash the object down onto the base. There are two types of Diamond Hitches, a single, shown here, and a double diamond hitch which is not shown.
