Slue

Slue refers to a type of knot used in sailing and climbing, characterized by its simplicity and effectiveness in preventing a rope from running out. It is often described as a stopper knot, meaning its primary function is to create a bulky point on a rope that will not pass through a hole or fairlead. The construction of a slue involves forming a simple loop and then passing the working end of the rope around the standing part before tucking it back through the original loop. This creates a knot that, while easy to tie, can be difficult to untie after being subjected to significant strain.

The name "slue" is not as commonly recognized as some other stopper knots like the figure-eight or the overhand knot. However, it is a functional and reliable knot for certain applications. Its advantage lies in its minimal bulk when tied loosely, allowing it to be adjusted before tightening. When pulled tight, it forms a secure stopper. The knot's effectiveness is dependent on proper tying technique, ensuring the turns are snug and the working end is properly secured. While not a primary knot for critical load-bearing situations, it can serve as a useful backup or for non-critical applications where a simple, effective stopper is needed. Its construction makes it less prone to jamming than a simple overhand knot, though it can still be challenging to release under heavy load.
