Yet, another midline eyeknot

[Kost_Greg]

Hi Ychan, you are quite right, i stand corrected, my sight is rather poor lately.

However, if you wish, feel free to include this bend at your previous reply in your toggles-Horns-like folder, with a name of your choice, as it still remains nameless.

Best regards

Hi all,

I present here with this Moth Midline Loop Knot. Recently amongst my knots discovery, I found this one simple and interesting, non-jamming. It can be untied easily by loosening the SParts. The nub is closed tight when both the SParts are loaded. When untying it, just open the nub like open the Mocha Loop Knot in the way like open a book.

Hi Ychan, at first, happy and creative new year to you and to all IGKT members.

I found this one simple and interesting, non-jamming. It can be untied easily by loosening the SParts.

I concur to all that, quite simple with a very easy TIB tying method that i have found (three bights, left, central, right as a starting configuration, more when i have some images), certainly non-jamming, but in my view, the pliable component here is the main collar that i'm illustrating in the attached image, meaning that this is the first component that you are going to press to loosen the knot, not the SParts that you mention above.

The nub is closed tight when both the SParts are loaded.

You certainly load the Sparts to achieve the dressing you show in third and fourth image, but i'm not really sure if this knot is  most relevant for biaxial loading applications (bends), because the main collar is the only component that maintains the structural integrity of the core.

I also noticed some core distortion at medium through loading (SP to SP), which i usually take into less consideration, as i am mostly interested in the eye loading profile of an inline knot, and in this case, the eye strain appears to leave a stable and solid core when employing both SPs.

If the nipping loop is flipped as i propose in the attached photo, one might acknowledge a more bowlinesque form of the original knot, which i, for example, am able to read and better understand.

Thanks for this interesting tangle, i owe you a TIB tying method , and a slightly different dressing from yours.

TIB tying method for the moth inline eyeknot

1. Form the three bight configuration, left bight, central bight (final eye), right bight, and place the right bight over the left bight (stage 1).

2. Form another bight at the left eye leg continuation of the central bight, and feed it down through the  two bight formation (stage 2).

3. Reeve the central bight through this very bight from the previous stage.

I think with this dressing the nipping loop is more noticable, with its two rope diameters passing through it, following the bowline rule.

You may also notice the importance of the main collar for the integrity and the loosening of the core.

It does not link directly to SParts, retaining its pliability at heavy stress.I guess it requires some good pre-tightening before using the knot.

Perhaps your dressing, is more resistant to bi-axial distortion, and you may get it by flipping the nipping loop and rearrange the SParts.

Hi Kost_Greg

I have tied your midline eyeknot. I find it is not my Moth Midline Loop Knot. I think it is your another creation.

If you mean that the slightest modification in knot's geometry, brings about a completely different knot, maybe i would agree with your claim.

However, if you think that there isn't any topological correlation between the two knots, with just  a slight fiddling of the nipping loop with less effort, as i described it previously, then i have to disagree, because i have established this correlation more than fifty times, which makes me 100% sure.

Let me put it another way. If i follow the steps of the tying method at reply#78, is it feasible to create one of your configurations at reply#76, let's just say the one in your first image, yes or no?

[siriuso]

Hi Kost_Greg

Re. #78 and 79, I just point out that your inline eyeknot is not my Moth Midline Loop Knot because you use the name Moth Inline Eyeknot. Thus confused me that the TIB tying method is Moth Midline Loop Knot. I have admitted it is different from mine.

Yes, the configurations of the tying steps at reply#78 can be turned to the configurations at reply#76.

Most Midline Loop Knots have their nub being strangulated by their SParts. Moth MLK has not, its' SParts grab the lower part of the main collar, so the knot can be easily untied by retreating the SParts and free the loop from the collar.

Your Moth IEK also can be easily untied by flipping the collar over and free the eye/loop. But its' SParts grab/strangulate.

Hi Ychan

I think we have an understanding here, for your consideration, i didn't launch the knot at reply#78, as my own creation, it was just simply originated from your configuration, as a different dressing, and that was the reason me using your selected moniker, it was not my intention to hijack it.

Let's just say, it is just a variation of the moth with just a slight core modification.

Of course, it goes without saying, that if you have developed a TIB tying method, that leads directly to your structure, by all means, do upload it.

Thanks.

Hybrid butterfly forms

I am bringing to mind that this type of structures employ interlocking, figure eight and overhand components.

Some or most of us, when tying the 1053 butterfly, we usually arrive at the conventional first image figure, just before the final reeving of the central bight down through both interlocking loops.

Instead of doing that, a crossing knot is formed at the left, S loop continuation, while the central bight is driven only through the crossing knot and down through the right Z loop, according to the second figure, which leads to the cinched and well dressed structures of the next two images.

It is certainly an interesting scheme with sufficient stability towards all loading directions, and in my view, a more manageable, figure eight component, at heavy strain.

Of course, the overhand is still there, ready to rock, but for fussy knotters (like me ), the good thing is that it might be able to leave room for a couple of modifications, that neutralize its jamming function.

[Kost_Greg]

I was quite surprised to find out that the previous inline knot at reply#83, appears to maintain the symmetrical properties of the butterfly knot despite the distinction of the two components that make up the core structure (figure eight/ overhand, overhand/overhand for 1053).

In others words, it actually becomes feasible to transition from the midline, to the end of line profile and vice versa, employing only TIB nub maneuvering, with none at all, eye manipulation.

If it's going to be used in this unprocessed form, i would suggest to be loaded from the figure eight side.

Now, inducing some eye manipulation, to dispense with the remnant overhand, one might convert the inline structure to a double splayed loop bowline variant, by simply folding the eye and pulling the eye leg continuations up through the eye, which now becomes the bowline collar (first two images).

If a geometrically shaped, inline profile, free of overhands is a necessary condition, then the eye legs of the knot at reply#83, shoud swap positions, and the eye should be reeved from the overhand side.


Interpretation of eye leg swapping/eye reeving through the overhand side.

In more detail, start with the figure eight, eye leg continuation by placing it over the other.
Then extend the other overhand eye leg continuation, forming a bight, fold it under the core nub, and pass the eye throuh this very bight.

Of course, there is another TIB tying method, which leads directly to third, fourth image, midline knot formation.

i really like your use of the arrowheads in the illustration,
which is much clearer than use of a single line and arrow

Hi all,

Showing here is the February Butterfly Midline Loop Knot. The loop passes through three eyes.

Thank you Alana, i ain't really known for my illustration skills, but i'm trying my best.

Hi Ychan, i'm glad to see you experimenting with these forms.

I think it's somewhat arbitrary to use a plain butterfly descriptor for two reasons.

1) None of your loops are interlocked to one other.

2) If you remove the first turn of the left link, (shown in the attached image), you will find that the parent knot is the false butterfly.

So, in my view, an identifier like "false", before the butterfly term, would be more meaningful.

In other respects, the knot is pretty good, clearly an enhancement to false butterfly, because one of its overhand components, more specifically the left one, is being transformed to a more pliable form of a figure nine, with this extra turn, and an "easy to handle", figure nine collar.

Loading it from the figure nine side, in my view, would be a jam-safe way.

Well done!!

Hi Kost-Greg

I have had tried and tied several knots like the February Butterfly Midline Loop Knot including this February Butterfly Beta Midline Loop Knot. I did not put it up here because of the interlink loops or non-interlink loops as Moth Midline Loop Knot and Moth Beta Midline Loop Knot. I like Moth MLK more than Moth Beta MLK. Moth has no interlink loops, but Moth Beta has interlink loops. Same as these February Butterfly MLK and February Butterfly Beta MLK.

Hi Kost_Greg

I like the right SPart be placed under the diagonal line that forms the appearance of a Clove Hitch. That is why I like February Butterfly MLK.
