best knot for hanging... probably asked before, but new details never hurt

[SufferingInDenmark]

it should increasingly tighten as you sink down, right?
and using soap i also heard helps tighten it even more...
what avout the material of rope?

i heard people debating between slipknnot and another one i think is called hangman knot (not sure about the name, probably wrong)

The slip knot and the noose knot can both be used for hanging. Each tightens with pressure from opposite ends of the rope. It really does not matter which you use, as long as you use the correct one for your setup. I personality used a slipknot as it runs easier but I had to tie it backwards for it to work correctly.

See the first post here and the pages they link to:

Distinction: Slip Knot vs. Noose Knot

I am planning on completing the Intermediate Knots practice and noticed an important detail in the official Bushclass video by Skab I was confused as to specifically which end of the rope was to be formed into a bight and passed through the loop, so I searched for other resources on "slip...

Slipknot

The slip knot and the noose knot can both be used for hanging.

It's called the Noose Knot, which should not be confused with the Slip Knot or a Hangman's Noose. The only difference between the Noose Knot and the Slip Knot is which end is the sliding end, but it's an important difference (otherwise, they are exactly the same). The Noose Knot is used for tying a noose – or in other words, a loop that tightens under tension. The Slip Knot is used for tying a temporary stopper knot that's easy to untie. Here is a video explaining the difference.

A stopper knot must be added on the tail end of the Noose Knot (on its own, the Noose Knot can be unreliable). By the way, a Noose Knot with a stopper knot can also be called an Arbor Knot. An Arbor Knot is just a Noose Knot with an Overhand Knot stopper. See these videos for how to tie it: Video 1, Video 2.

Apart from the Noose Knot + stopper knot combo, I find that the Poacher's Knot works very well too. The Poacher's Knot is secure on its own, so a stopper knot is not strictly necessary, but one can be added, of course. Adding one has no drawbacks – it can only make the knot more secure.

I wouldn't use the Hangman's Noose. It's too stiff and doesn't tighten very easily under load.

what avout the material of rope?

Polypropylene (PP) and polyester (PES) are probably the two best choices. Both are very strong and highly stretch-resistant. If you're getting a braided or double-braided rope, look for those materials. Nylon (polyamide) should also work. It's a bit more stretchy, but not so much that it should cause a problem.

Interestingly, static or semi-static climbing ropes are often made of nylon and can be highly stretch-resistant. So if you go for a climbing rope, look for static or semi-static ones, and don't focus too much on the exact material.

How much length of rope should you use in relation to your height and weight?

good question

How much length of rope should you use in relation to your height and weight?

It's best to have more rope available; when you find the ideal spot (anchor point), you can cut it to your liking (or leave the excess rope hanging if you don't want to cut it)

Choose a synthetic material like polypropylene or polyester; they support a lot of weight and are strong. Also the noose knot will slide more easily. Check the breaking load before purchasing. Also check the strength of your anchor point, it must support your entire weight.

Always talking about FSHanging.

Drop hanging is used in executions and involves other types of preparations. And we're not military professionals to carry it out properly. Even they have made mistakes, causing prisoners to suffer through poor technique and calculations.

Hello everyone,

My first post here. I have about the same question as op, so I'll jump right in here instead of starting a new topic. Hope that is OK.

I made the recommended Noose Knot and it tightens alright when pulling the rope. But only to a certain point (see attached picture). After that, no matter how hard I pull (to the left in the picture) , it won't tighten fully around this object I am using here. It would if I would pull towards the top of the picture, but that's not the way it will be.

This seems to be the physics of it. But I haven't seen this issue mentioned on here.

I did try it out around my neck and pre-tightened the knot as far as possible. Then, while standing, I threw the rope over a pull-up bar and pulled it while also leaning into the noose. It worked surprisingly well and I passed out fast and unplanned (my previous trials while sitting on the bed didn't do much beyond some blurry vision).

So it is generally working. But I am still unsure whether the noose would continue to tighten enough, or stay stuck at the pre-tightened position.

You may have tightened the knot too much near the object and that's why it's sticking instead of sliding easily.

Try loosening it a little and placing it against the object. Or lubricate that section of the rope, to see if it can close better.

In any case, note that the object is hard, your neck is soft, the rope will penetrate it, reducing its diameter.

The carotid arteries are on the sides of the neck, the weight of your body will cause them to be compressed when the knot closes itself (since the knot will be behind the neck)

I've been experimenting with this knot too, and I can confirm these observations. That is how the knot behaves. Here is what I think about it.

All types of nooses behave like this. As you said, this is the physics of it. This is as good as it gets. For example, you can tie a Running Bowline — which doesn't close and bind on the load end at all — and it will still behave the same way. It's impossible to tie a noose that tightens perfectly when the rope is pulled away from it. Considering this, the Noose Knot with a stopper knot (also called an Arbor Knot) is still one of the best knots to use in my opinion.

If it works well and you pass out quickly (as you mentioned), I don't think we need to worry about this. It'll work even better under full load, regardless of the above 'issue'. And that's good enough. (I put 'issue' in scare quotes, because I don't think it's a real issue.)

That said, if we really want to analyse the mechanics of it thoroughly, and not just accept that it's good enough, consider the following.

In hanging, it's not exactly the same situation as in your picture. In your experiment on the picture, you're probably holding the object in a stable position. However, during hanging, there's nothing preventing your neck from turning and twisting, which may help the knot tighten more firmly. As the Noose Knot tightens, it may cause the neck to turn slightly, which helps the knot tighten even more, and so on. This behaviour is what causes the knot's position to shift slightly under full load. This is just theory, and how strong this effect is in practice depends on other factors, but the effect is there.

OK, thank you both for the input @JesiBel and @AreWeWinning.

I just tried it around my thigh and it does help some to have soft tissue instead of a hard object and also with the leg moving it did close some more bit by bit, even if not perfectly. So this should be good enough then, as you say.

I suppose the alternative would be having a ring or fixed noose on one end and pull the other end through it, dog leash style. Then again, the Noose Knot seems to do the job just fine when looking at statistics, but rings are hardly ever mentioned. Maybe better to go with tried-and-true.

If you are looking for an alternative to the noose knot, "dog leash style";

@Worndown shared a good example. Look, the blue rope photo:

Post in thread 'Eye Splice Rope'

Eye Splice Rope

For hanging, partial or other, I struggle a lot with the knots. Would getting a rope with an eye splice or thimble work? Or just making an eye splice/thimble on the rope itself, allowing it to tighten by being pulled through the thimble? Then you ust pull the rope through the eye splice loop...

If there is no friction in the knot or eyelet the angles between the three "legs" of the rope are equal, 120 degrees. This means also that the forces in the three rope legs are equal too, your bodyweight, if you hang full. This is the maximum you can get in terms of force. Due to friction, the force is normally a little less but by far enaugh. Maximum 300 degrees of the neck can be in contact with the rope, that's exactly what your foto shows. The elasticity of the tissue did not change anything. The difference of a real hanging situation is, that the noose and the bending is not in one plane like it is on your foto, the noose is bent up to the knot.

Thank you! If this is like it's supposed to be, I'm happy.
