Is The Alpine Butterfly Knot Stronger than Other Knots?

April 5, 2026

Quick Answer

The Alpine Butterfly Knot is one of the strongest stopper knots, capable of holding up to 3.2 times its own weight in a controlled test, making it a reliable choice for load-bearing applications.

Characteristics and Uses

The Alpine Butterfly Knot is a stopper knot used to prevent a rope from sliding along another rope or object. It is particularly useful in applications where a high level of strength and security are required, such as rock climbing, search and rescue, and sailing. The knot is also resistant to jamming and can be easily adjusted.

Tying the Alpine Butterfly Knot

To tie the Alpine Butterfly Knot, begin by creating a loop in the working end of the rope. Pass the working end under the standing part of the rope, then over the standing part and through the loop. Pass the working end under the standing part again, then over and through the loop. Pass the working end through the existing loop from the underside, then pull the working end to tighten the knot. Repeat the process on the other side of the standing part to create a secure stopper knot. The final result is a compact, symmetrical knot that can withstand significant loads.

Comparison to Other Knots

In comparison to other stopper knots, the Alpine Butterfly Knot is stronger and more secure than the Blood Knot and the Improved Clinch Knot. It is also more resistant to jamming than the Bowline Knot and the Figure Eight Knot, making it a popular choice for load-bearing applications. When properly tied, the Alpine Butterfly Knot can hold up to 3.2 times its own weight, making it an excellent choice for securing ropes in high-stress situations.
