Alpine butterfly

An Alpine butterfly is a specialized knot used in climbing, caving, and rescue work to securely connect three rope ends, forming a symmetrical loop. It creates a strong, stable, and adjustable connection that distributes load evenly, preventing the ropes from slipping or shifting under tension. This knot is valued for its strength, ease of tying and untying, especially when the ropes are under load or vary in length. The Alpine butterfly is a vital tool for creating secure loops in multi-strand ropes, often employed in scenarios requiring load distribution or bail-out points.
