fisherman’s bend

The fisherman's bend, also known as the anchor bend, is a strong and simple knot that is useful for attaching a rope to an object like a ring, hook, or anchor. It is made by taking two turns of the rope around the object, then passing the end back under both turns to create a pair of half hitches. This knot is designed not to jam or slip under strain and can be easily untied. However, if not under strain, the free end may slip loose if not secured. A similar knot, the studding-sail halyard bend, is used to secure a rope to a spar.1234
