Which knot is used to secure the end of the rope to an object?

The knot that is commonly used to secure the end of the rope to an object is the bowline. This knot creates a fixed loop at the end of the rope, which can be easily tied and untied even after it has been under load. The bowline is particularly advantageous because it does not slip or jam, making it reliable for various applications in firefighting and rescue situations.

In many scenarios, such as securing a line to a tree, pole, or safety harness, the bowline provides a strong, stable connection that is secure enough to hold weight without sliding or loosening. It's highly valued in emergency services for its dependability and ease of use in high-pressure situations.

While the clove hitch is often used for temporary securing of a line to an object, it can slip under loads that are not directly in line with the knot. The sheet bend is primarily used for joining two ropes, while the square knot is typically employed for tying two ends of the same rope together but does not create a loop for securing to an object. Each of these knots has specific applications, but for the purpose of securing a rope end to an object, the bowline is the most effective choice.
