The icicle hitch works very much like the Prusik knot and we tend to use them interchangeably. In our experience it’s hard to predict which one will work better in a given situation.
The Prusik is easier to tie and inspect, and we find it more attractive.
The icicle hitch is sometimes used to suspend bamboo poles horizontally, which makes us nervous. It’s really only designed to take load along the axis of the pole.
1Go behind and around the pole four times, moving up the pole with each wrap.
2Cross behind the standing part.
3Go behind and around the pole, this time below the standing part.
4Cross behind the standing part again.
5Go around and behind the pole.
This wrap should lie right below the wraps you made in step 1 and should exit just below the standing part.
6The icicle hitch is only secure when loaded vertically.
When fully loaded, the wraps will tend to spread out along the pole.
This knot doesn’t appear in ABOK.
