The adjustable bend [1] is a bend knot that is easy to lengthen or shorten.
A rolling hitch is used to tie the end of each rope to the standing part of the other. Clifford Ashley suggested it for tying guy ropes.
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.
The fisherman's knot is a bend with a symmetrical structure consisting of two overhand knots, each tied around the standing part of the other. Other names for the fisherman's knot include: angler's knot, English knot, halibut knot, waterman's knot, and true lovers' knot.
The butterfly bend is a knot used to join the ends of two ropes together. It is the analogous bend form of the butterfly loop, in that it is the butterfly loop with the loop cut. The observation that the butterfly loop is secure enough to isolate a worn or damaged section of rope within the loop indicated that the bend form of the knot would be similarly secure.
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 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. The word grief does not carry its usual meaning but is a portmanteau of granny and thief.
Hunter's bend is a knot used to join two lines. It consists of interlocking overhand knots, and can jam under moderate strain. It is topologically similar to the Zeppelin bend.
The Carrick bend, also known as the Sailor's breastplate, is a knot used for joining two lines. It is particularly appropriate for very heavy rope or cable that is too large and stiff to be easily formed into other common bends. It will not jam even after carrying a significant load or being soaked with water.
The anchor bend is a knot used for attaching a rope to a ring or similar termination. The name is a misnomer, as it is technically not a bend, but a hitch.
The diamond knot is a knot for forming a decorative loop on the end of a cord such as on a lanyard. A similar knot, also called the diamond knot, is a multistrand stopper knot, that is similar in appearance. To avoid confusion, it is advisable to call this knot the knife lanyard knot. This knot is a four strand diamond knot implemented in two strands. The knife lanyard knot is "tied alike" the Chinese button knot, "but they are worked differently."
The sailor's knife lanyard knot, also called marling-spike lanyard knot, single-strand diamond knot, two-strand diamond knot, and Bosun's whistle knot.
The sheet bend is a bend. It is practical for joining lines of different diameter or rigidity.
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.
A beer knot is a bend used to join tubular webbing. Its most common application is in constructing slings used in rock climbing. Compared with the water knot, it has the advantages of a higher strength, smaller profile, and a cleaner appearance due to the lack of free-hanging tails. However, the beer knot can be more difficult to tie than the water knot, and one of the tails is hidden from view, making safety checks for adequate tail length more difficult.
The offset overhand bend is a conceptually simple and easy to tie 'end-to-end joining knot'. It is formed by holding two rope ends next to each other and tying an overhand knot in them as if they were a single line. Due to its common use in several fields, this bend has become known by many names, such as thumb knot, openhand knot, one-sided overhand knot or flat overhand bend (FOB), though the terms "one-sided" and "flat" are considered incorrect.
The Albright special or Albright knot is a bend used in angling. It is a strong knot used to tie two different diameters of line together, for instance to tie monofilament to braid. The Albright is relatively smooth and passes through guides when required. Some anglers coat the knot with a rubber based cement to make it even smoother and more secure.
The Flemish bend, also known as a figure eight bend, a rewoven figure eight is a knot for joining two ropes of roughly similar size.
Ashley's bend is a knot used to securely join the ends of two ropes together. It is similar to several related bend knots which consist of two interlocking overhand knots, and in particular the alpine butterfly bend. These related bends differ by the way the two constituent overhand knots are interlocked.
The triple fisherman's knot is a bend knot, used to join two ends of rope together. It is an extension of the double fisherman's knot and is recommended for tying slippery, stiff ultra-high-molecular-weight polyethylene (UHMWPE) and aramid cored ropes.
The harness knot is a general purpose bend knot used to join two ropes together. The knot can be tied under tension and will not capsize.
