Figure 9 knot ok?
|
Somewhere (maybe here) I read about using a "figure 9 on a bight" (wrap twice around the standing side of the rope before pulling the loop through, instead of once) in situations (eg toprope anchor), because the 9 was easier to untie than the 8 after it's been loaded. Anyone aware of any problems or drawbacks with the figure 9? |

Properly called the 'Stevedore' knot. Typically used as a stopper knot on a single rope end. Don't see why it couldn't be used on a bight though. |
|
I use figure 9's all the time when I know it will be weighted. I use it with rope, cord, and dyneema slings. |
|
Bowline on a bight seems easy to untie... |
|
Interesting. I'd never heard of this knot. I always thought a figure 9 was a climbing move |
|
it works absolutely fine .. cavers use it |
|
keep wrapping (figure nine, ten, eleven, so on) it to make it even easier to untie, or to use up more cordage to create a higher master point. |
|
A figure 8 is easy to inspect. A 9 is harder but if you look at them enough you could see if it is tied right. |

There is some discussion whether the knot will "roll" if you cross load the loop by clipping a q-draw between the loop and a bolt, for example. |

Makes more sense to call it a figure 9 so thats what I will continue to call it. Sorry to your buddy Steve Dore. |

Figure-9 on a bight - |
|
I use it with webbing because fig 8 tends to make the bight come out at a 90-degree angle to the strand and fig 9 corrects that. Not sure about actual knot strength, but the figure 9 just looks cleaner and loads more evenly |
