Italian half knot is also called Italian half buckle. Strictly speaking, it is not a closed knot. This knot can only be completed with the cooperation of the lock. It can be used to ensure the top rope, but it can only be used without impact, which is not suitable for pioneer protection. When you lose or don't bring your equipment, you can use the Italian half knot to descend, but the rope is easy to get entangled.
Italian half knot+pear-shaped main lock = equal to a simple protection or lowering device. Italian semi-buckle is easy to operate and efficient, and is often used to protect the top rope of mountaineering teams. If necessary, the Italian half buckle can also be used for descent. The formed Italian half knot will turn over with the stress direction, and the brake rope will be pulled by hand parallel to the stress rope when braking.
Introduction of common knots:
1, rabbit ear knot
Rabbit ear knots are 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.
2. splayed knot
In many cases, the figure-eight knot is a general stop knot, not an ordinary backhand knot. In navigation and rock climbing, the figure-of-eight knot is very important, because the rope is needed to stop the knot to prevent the device from falling off.
3, eight-character back knotting
The figure-of-eight back knotting is often used in rock climbing and cave exploration (the rope tension is moderate), and a fixed rope loop is formed at the end of the rope or around the object. Unbinding is relatively easy and firm, but it will become difficult to unbind after overload.
