Also known as: Triple Sliding Hitch
History: Dr. Karl Prusik created the Prusik Knot in 1931. He was a former president of the Austrian Mountaineering Club. It is often misspelled as “Prussik.” It looks like a knot that Ashley described for hoisting a spar. (ABOK # 1763, p 300), but Ashley did not name this knot and did not describe the slide and grip feature. The knot requires a “Prusik Loop”.
Uses: The principal use of a Prusik Knot allows climbers to ascend a rope, a technique known as “Prusiking.” Two Prusik loops slide up the static rope. A long loop reaches the climber’s foot. This lets the climber use leg power to ascend. A second, shorter loop attaches to the harness, allowing the climber to sit. In rescue work, rescuers can pull up a climber using a Prusik loop. This loop holds a pulley block on a climbing rope.
