Jamming (knot)

This page explains commonly used terms related to knots.

A bend is a knot used to join two lengths of rope.

A bight has two meanings in knotting. It can mean either any central part of a rope (between the standing end and the working end) or an arc in a rope that is at least as wide as a semicircle. In either case, a bight is a length of rope that does not cross itself. Knots that can be tied without use of the working end are called knots on the bight.

Binding knots are knots that either constrict a single object or hold two objects snugly together. Whippings, seizings and lashings serve a similar purpose to binding knots, but contain too many wraps to be properly called a knot. In binding knots, the ends of rope are either joined together or tucked under the turns of the knot.

Another term for the working end.

A knot that has capsized has deformed into a different structure. Although capsizing is sometimes the result of incorrect tying or misuse, it can also be done purposefully in certain cases to strengthen the knot (see the carrick bend) or to untie a seized knot which would otherwise be difficult to release (see reef knot).

Chirality is the 'handedness' of a knot. Topologically speaking, a knot and its mirror image may or may not have knot equivalence.

A decorative knot is any aesthetically pleasing knot. Although it is not necessarily the case, most decorative knots also have practical applications or were derived from other well-known knots. Decorative knotting is one of the oldest and most widely distributed folk art.

Knot dressing is the process of arranging a knot in such a way as to improve its performance. Crossing or uncrossing the rope in a specific way, depending on the knot, can increase the knot's strength as well as reduce its jamming potential.
