Which knot is commonly used as a friction hitch for ascending a rope?

• A. Water Knot
• B. Prusik Loop
• C. Figure Eight
• D. Half Hitch

Answer: (B)

A friction hitch used for ascending a rope relies on a knot that tightens and grips the rope when loaded, yet can be moved up the rope when you shift your position. The loop version of the Prusik knot fits this need perfectly. It’s tied from a length of accessory cord into a small loop that wraps around the main rope. The multiple turns around the rope create friction, and because the loop is smaller in diameter than the rope, the knot bites into the rope under load and holds your weight. When you stand up and reposition, the load on the hitch changes, allowing it to slide more easily so you can advance the loop, then re-seating as you continue upward. This combination of reliable grip under load, ease of adjustment, and repeatable performance makes the Prusik loop the go-to friction hitch for rope ascending. The other options serve different purposes. The water knot is used to join two ends of webbing or rope ends; it isn’t designed to grip and slide on a rope for ascent. The figure eight forms a stopper or creates a secure loop in various climbing contexts, but it doesn’t function as a friction hitch for climbing up a rope. The half hitch is a simple binding around a rope, not the controlled, load-responsive grip that a Prusik loop provides for ascending.
