What is the purpose of a bend knot?

A bend knot is specifically designed to join two lengths of rope together securely. This type of knot is essential in various applications, particularly in rope rescue operations, where it is crucial to ensure that the connection between two ropes is strong and reliable. Using a bend knot allows rescuers to extend their reach or increase the length of the rope when needed, such as when performing a rescue at height or over a distance.

In contrast, other options describe purposes better suited for different types of knots. For instance, securing a load to a fixed point typically involves knots such as the bowline or clove hitch, which are designed to create secure, fixed points rather than joining two ropes. Similarly, creating a loop in the rope pertains to loop knots, such as the bowline, which is not primarily meant for connecting two separate pieces of rope. Thus, as it pertains specifically to connecting two lengths of rope, a bend knot is the appropriate answer.
