Help Did I tie a slip knot wrong all this time?

[PatheticLoner]

I learned how to tie slip knot from this video. As you can see, he does only one wrap.


But then I saw this guide where the author suggests making several wraps

I tested it on my wrist, and the knot with more wraps provides much more pressure than the knot with only a single wrap. Does that make sense? I didn't see this mentioned anywhere for some reason

The title is kind of a clickbait. Obviously, it will work with one wrap as well, but multiple wraps can make you pass out more quickly in theory. Maybe I am hallucinating this though

The knot on the 101knots.com link is not a Slip Knot, but a Poacher's Knot (also called a Double Overhand Noose). Also, when you form a self-tightening noose, that's not a Slip Knot either, but a Noose Knot. A Noose Knot with an added stopper knot at the tail end is called an Arbor Knot. Adding a stopper knot is essential! Without adding one, the Noose Knot in itself is unreliable.

The knot on the right in your picture is probably a Scaffold Knot, which has not one, not two, but three wraps.

Adding more wraps won't provide more pressure when the rope is under load. All it does is that it makes the knot lock in a tight position more firmly, and makes it more difficult to release and untie. In full suspension hanging, this doesn't matter. In partial suspension, it might make escape less likely in theory, if that's what you meant.

The Noose Knot on the left in your picture doesn't have a stopper knot at the free end. This is a major mistake, and could be the reason why the knot didn't provide enough pressure when you tested it. If you add a stopper knot, as shown in the YouTube video, the knot becomes secure, and it's suitable for use. Although it isn't shown like that in the video, tie the stopper knot as close to the main knot as possible to avoid any initial slippage.

Another thing to note is that adding more wraps not only makes the knot lock in a tight position more firmly, but it also makes it tighten less easily, because more wraps create more friction. This isn't necessarily a problem, and as long as it's a self-tightening noose, it should work well.

When you test it on your wrist, you probably pull on the rope and move it sideways back and forth, which helps tighten the noose. However, in an actual hanging scenario, the noose is only pulled downward, so it won't always tighten fully. You can test this on your wrist too if you just pull the rope away from it, without pulling or moving it sideways. This is just another interesting thing, and it illustrates that there isn't a great difference between various knots from a practical point of view. The most important things are that 1) you use a secure knot, and 2) it's actually a self-tightening noose.

Not sure if this answers your questions, but these are my experiences from testing these knots.
