How to tie a prusik knot
There are several variations on these types of hitches and it is common for climbers to carry several loops of line or continuous slings to form these fast handy connections. A prusik can form a strong anchor that doesn’t slide down a leg or steep diagonal. These are often tied in place of a mechanical rope ascender.
