For climbing purposes, ALL SORTS of equipment is used, not just rope+knots. Some prominent metal bits include: SLCD, figure eights, and of course carabiners.

However, there are some places where pure rope+knots are used in climbing.

I find climbing very interesting because it crosses a red-line that usually is never crossed in structural engineering — using devices to "suspend overhead loads". Put another way, it one of the few places that rope is made part of a life-critical system. (For climbing, the situation is reversed: rather than the load being suspended over a human's head, the load that's being suspended IS the human. Either way, if the rope breaks, the human is injured.)
