Quick Answer
The Alpine Butterfly Knot is occasionally used in alpine situations, particularly when connecting two ropes together, but it is not a primary or widely used knot in this context.
Frequency of Use
The Alpine Butterfly Knot is not as commonly used as other knots in alpine situations. According to the International Climbing and Mountaneering Federation (UIAA), it is mentioned in their Knots Guide, but only as an alternative to the more commonly used Water Knot. This suggests that the Alpine Butterfly Knot is not widely taught or used in the climbing community.
Applications
When the Alpine Butterfly Knot is used, it is typically in situations where a reliable connection between two ropes is required. The knot is well-suited for this purpose due to its high strength and resistance to jamming. In alpine situations, the knot can be used to connect two ropes together, such as when joining a climbing rope to a rappel rope. The recommended ratio for the Alpine Butterfly Knot is a minimum of 12 turns, with a minimum of 6 turns for each rope.
Comparison with Other Knots
Compared to the more commonly used Water Knot, the Alpine Butterfly Knot has a few advantages. It can be used with ropes of different diameters and can be adjusted to accommodate different rope lengths. However, the Water Knot is generally faster to tie and requires less equipment. Ultimately, the choice of knot will depend on the specific needs of the situation and the preferences of the climber.
