How to tie the One-way Knot or One-way Bend.
The One-way Knot is a special purpose bend that can be used to join two lines when it is known that the knot will have to pass through a shackle or pulley. Because the tails or working ends of the knot all face in the same direction, the knot is less likely to get stuck in the hardware it must pass through.
A similar knot is the Tucked Sheet Bend which might be just a tad more robust, useful if the knot is to be dragged through brush or over rocks.

One-way Knot Tying Instructions
- Form a loop in the end of the rope that goes in the direction of the pulley or other hardware that the knot will be passing through.
- Pass the working end over the standing line and feed it up and through the first loop, as in a Figure Eight.
- Insert the working end of the line to be joined adjacent to the working end of the first rope where it exits the knot and begin to retrace the first knot.
- Keeping on the same side of the first rope exit the first loop alongside the first rope. Leave fairly long tails with the both ropes and pull all four ends tight to set the knot.
