Belaying devices use a combination of friction and pinching to produce a braking effect on the rope and a device’s design dictates which effect will predominate upon loading. Devices relying principally on friction (e.g. Figure-of-8) will t...

Salewa invented the principles behind most modern day belay devices in the early 70's, with the original sticht plate. This had a tendency to jam, so a spring was added, thus relieving the problem. The sticht plate is still very good, but there are ... The krab hole has been stretched to work better as a belay device.

You could try sliding down a rope with your bare hands, but it probably wouldn't feel to great, or work well either. The rappel system described provides plenty of friction.

However, the bent gate also makes it easier for the gate to work itself open, ... A belayer's job is to hold the rope to stop a falling climber, which is difficult without the aid of a belay device---an object capable of stopping the rope or passing it through smoothly. There are many such belay devices, and are all easy to...
