What is commonly referred to as the 'king of knots'?

The bowline is commonly referred to as the 'king of knots' due to its versatility and reliability in securing a fixed loop at the end of a rope. This knot is particularly valued because it does not slip or jam under load and can be easily untied after being under strain, making it ideal for various applications, including sailing, climbing, and rescue operations. Its simplicity in tying and the strong yet non-slip nature of the loop it creates further contribute to its reputation.

The bowline is useful in situations where a secure knot is necessary, but the ability to untie it easily after use is equally important. This makes it a preferred choice for many professionals and enthusiasts in fields where rigging and knot tying are essential skills. In contrast, while other knots like the square knot or clove hitch also serve their purposes, they do not exhibit the same level of reliability and ease of use that the bowline provides in creating a secure, fixed loop.
