What knot forms a loop around an object, will NOT tighten but will be easy to take apart?

The bowline knot is specifically designed to create a fixed loop at the end of a rope, which will not constrict or tighten under load. This characteristic makes it particularly useful in situations where a secure loop is needed, but where ease of untethering is also essential. The bowline’s structure consists of a single loop formed by threading the working end of the rope through a loop created with the standing part, followed by wrapping it around the standing part and back through the loop. This design ensures that the knot will hold under weight without slipping but can be untied with relative ease even after bearing a load.

The importance of the bowline knot lies in its versatility; it is often used in boating, climbing, and rescue operations where a reliable loop is essential, but the ability to quickly untie the knot is equally vital. This knot does not jam, which is a common issue with other types of knots, making it an excellent choice for applications requiring frequent adjustments or quick release.
