What is the name of a knot that is specifically designed to join two ropes?

The term for a knot specifically designed to join two ropes is referred to as a "bend." Bends are essential in rope rescue operations and various applications where you need to create a secure connection between two separate lines. Common examples include the double fisherman’s bend and the water knot, both designed to maintain strength while allowing for adjustments to the tension or length as needed.

In contrast, the terms "loop," "hitch," and "knot" do not accurately describe a knot that joins two ropes. A loop typically refers to a single rope formed into a circular shape, while a hitch is used to attach a rope to an object or another line, rather than to join two ropes directly. The general term "knot" encompasses various types, including bends, hitches, and loops, but it does not specify that the knot is meant for joining two separate ropes. Understanding the significance of a bend in rope rescue practices is crucial for effective and safe operations.
