The most common of all the knots used in rope rescue. Tied on a single rope it makes an excellent stop knot, more commonly tied on the bight, it forms a secure attachment point. When tied "re-rove" it secures the rope directly to an anchorage point.
The sequence to tieing a good knot is easy, just follow the following order:
- Choose the right knot for task
- Tie the knot correctly leaving sufficient tail for a stopper if required
- Dress the knot, ensuring the lay of the rope is not twisted or crossing over each other
- Tension the knot, easing all parts snugly together
- Check the knot visually
The figure of 9 knot, it's just the figure of 8 with an extra turn (8+1=9) hence the origin of its name. The knot is perhaps 1% or 2% stronger than the figure 8. Such a small margin it's not worth worrying about.

We do have figure 9 knots on our rapid deployment kits. The knot is pre-tied and tensioned. It takes a little longer to dress this knot and ensure that none of the lays are twisted.
