A knot is a metho for fastening or securing linear material such as rope by tying or interweaving. It may consist of a length of one or more segments of rope, string, webbing, twine, strap or even chain interwoven so as to create in the line the ability to bind to itself or to some other object - the "load". Knots have been the subject of interest both for their ancient origins, common use, and the mathematical implications of knot theory.
