:Work In Progress
UsageThe Alpine butterfly knot is a form of knot that is used by climbers and mountaineers.
It can also be used to isolate a worn section of rope.
HistoryKnown since ancient times, compared to other knots that might be used for the same purpose it is stronger (does not reduce the strength of the rope by as much), and is secure if the knot gets wet.
Advantages
  • Does not reduce the strength of the rope by very much
  • Will not slip (after initial settling)
  • Allows for the knot to be loaded three ways (each end of the main line and by the loop)
  • Relatively easy to undo after loading (more difficult if wet)
Disadvantages
  • Difficult to tie one-handed
  • Requires some training/practice to master
  • If tied using some methods there is a potential to trap the hand if the line is loaded unexpectedly
