Hi All,
        This "Unknown eye knot" is very simple, small and unique eye knot, If you are looking for a super secure
         and jam in permanently eye knot, you may like this one here, is good enough for general use, 謝謝 alan lee.

Nice work here Alan.
I like your TIB demonstration in the first video.
It might be instructive for Harold Kahl to look at your second video showing the alleged failure mode?
It is important to pay close attention to dressing and cinching of the ''unknown eye knot'.
I recall Ashley's famous sermon...

A knot is never 'nearly right'; it is either exactly right or it is hopelessly wrong, one or the other; there is nothing in between.

Please note these are Ashley's words not mine - I simply post it here because in this instance, it seems fitting!

While playing around with re-threading #1009 / #1046 (simple overhand eye knot) to an object, I stumbled upon this structure.
Tied in Sterling 8mm accessory cord, it seems to be secure and stable but, this is based on very limited analysis.
I have no idea of its resistance to jamming or what its jamming load threshold is.
...

Oh, lovely eye knot : concise, nice SPart curve,
and some chance that the base overhand will
be able to be loosend.

Long ago I too found this, and some similar versions
(diff. whether tail crosses over / under itself).

I could see this knot tied in some rope out in a
work yard of construction / marine / <whatever>

Now, for life-critical, out-of-sight, longer-duration,
and in-firm-smooth-climbing-rope uses, no, I concur
in your cautions.

(I think that I've a piece of found-on-the-coast 5/8"
laid PP with this knot put into it.  In large rope,
knots seem so HUGE!)

(And pulling on one leg only is one test of stability
and overall resistance to Bad Things, but not surely
a disqualifier overall.)

Yes - it would be interesting to determine the jamming load threshold for this 'nameless eye knot'.
I have no data or practical experience for this knot.
I suspect that the core overhand knot might resist jamming up-to-a-point. But what that 'point' is, I have no idea.

I also note that it has some passing resemblance to the #1010 derive 'Yosemite Bowline' - which might create an opportunity for a side-by-side photo in a knot exam paper (eg identify which knot is the 'Bowline' - tests if the student can identify a 'nipping loop').
