In cording, the interlacement of parts of one or more ropes, cords, or other pliable materials, commonly used to bind objects together.
Knots have existed from the time humans first used vines and cordlike fibers to bind stone heads to wood in primitive axes, and were also used in the making of nets and traps. Knot making became sophisticated when it began to be used in the ropes, or rigging, that controlled the sails of early sailing vessels, and thus became the province of sailors. Knots are still depended on by campers and hikers, mountaineers, fishermen, and weavers, among others.
