Common knot 1: Rabbit ear knot (also called double-stranded splayed knot) is often used to balance two ground anchors when climbing, and can also provide redundancy. Compared with many other double-loop knots, the rabbit ear knot is firm and safe, and the size of the rope loop can be easily adjusted by moving the rope from one ring to another. Each loop shares about 50% of the load. Any rope loop, any ground anchor and any mountaineering buckle are damaged, and the remaining ground anchor combinations cannot be used reluctantly.
Commonly used knot 2: Figure-eight knot (also called single figure-eight knot) In many cases, the figure-eight knot is a general rope knot, not an ordinary backhand knot. In sailing and rock climbing, the figure-eight knot is very important because it needs to prevent the device from falling off.
