Guys, if you are rock climbing, if I were you, I would pay more attention to ropes, grappling-hooks and other accessories. This is very important, and if I were you, I would be more responsible for this because there are many cases when people died because of such little things. I teach the basics of climbing and over time I have decided to devote as much time as possible to the basics of safety. I show the most reliable ropes and hooks and advise them to choose something suitable from the start at https://ladi6.com/grappling-hook/!
