What is the purpose of a butterfly knot?
The butterfly loop, also known as lineman's loop, butterfly knot, alpine butterfly knot and lineman's rider, is a knot used to form a fixed loop in the middle of a rope. Tied in the bight, it can be made in a rope without access to either of the ends; this is a distinct advantage when working with long climbing ropes.
Here's how to tie this knot.
- Pass the running end of the rope around the post or through the grommet.
- Bring the end over and around the standing part of the rope, then back through the loop that has formed.
- Continue taking the end around the standing part to tie another half-hitch (this time outside the loop).
