Knotting

Knotting is the practice of forming knots in rope, cord, thread, or other flexible materials. It includes tying, weaving, and securing lines for a purpose such as joining strands, fastening to objects, or creating adjustable loops. Knotting contrasts with knot theory, a branch of mathematics that studies the properties of abstract knots without regard to physical materials.

Knots are often categorized by function. Bends join two lines; hitches secure a rope to an object; stopper knots prevent a rope from slipping through openings; and loops can be made with slip knots or lanyards. Common examples range from the overhand and figure-eight knots to the square knot and bowline. Each knot has different strength, load behavior, and ease of untangling.

Applications span outdoor, maritime, and artistic contexts. Climbers rely on appropriate knots for safety; sailors and boaters use knots to rig lines; campers tie shelters and lash gear; fisheries, rescue operations, and textile arts such as macrame also employ knotting. Proper training and rope inspection are important, as some knots may slip, capsize a line, or fail under dynamic loads or moisture.

Historically, knotting has ancient roots in many cultures. The term knot, as a unit of speed, derives from measuring a ship’s velocity with a knotted line, known as a nautical mile per hour. In modern times, knotting persists in both practical crafts and decorative arts.
