What type of knot is commonly used for securing climbing gear?

The figure-eight knot is commonly used for securing climbing gear due to its reliability and ease of inspection. It creates a strong, fixed loop at the end of a rope and is often employed to connect a climber’s harness to a climbing rope or to create anchor points. Its structure provides confidence in high-tension situations, such as while rock climbing or mountaineering, where safety is paramount.

The figure-eight knot's simplicity allows those using it to quickly recognize if it has been tied correctly, making it a favored choice among climbers who need to ensure their knots are secure before taking on challenging climbs. Additionally, it can be easily untied after being loaded, which is another practical benefit in the dynamic environment of climbing.
