Inline Figure 8 knot

The Inline Figure 8 is a unidirectional, mid-line knot used to pull on a rope. It is most often used to create a mechanical advantage by running the tail of the rope through a fixed pulley and then back through a second pulley attached to the Inline 8. If it is pulled in the wrong direction it turns into a slip knot.

Awesome. I have not heard of this knot but it looks like a good alternative to an alpine butterfly.

Thank you! Very easy and straight forward.

is there any application where this would be a superior knot to the alpine butterfly?
