A "bend" knot is used to do what?

The definition of a "bend" knot aligns perfectly with its primary purpose, which is to join two ends of cordage or webbing together. This type of knot is essential in scenarios where two ropes need to be tied securely to ensure that they function as a single, stronger line. Bend knots, such as the square knot or sheet bend, are crucial in both rescue operations and general climbing activities where the integrity of the connection can be life-saving.

While other knots have distinct purposes—such as securing a single line, anchoring a rope, or guiding a falling object—bend knots specifically focus on the joining function. This characteristic makes them invaluable in search and rescue operations where lengthening a rope or using multiple pieces of cordage is often necessary for effective maneuvers.
