Hi All,
         Just another way to tie this Lee s 8 loop.         

         謝謝  alan lee.

  The angle of the "handle" is a little smaller that I would had wished ( about 60 degrees - I would prefer 90 degrees ), and the grip/contact between the Standing Part s first curve and the continuation of the returning/second eyeleg is a little less direct as I would had wished, but the combined effects of those two factors make a truly "adjustable" loop, indeed.

...after manual capsizing+manipulating, the knot can be transformed in ABoK#1045 !

...which is the end-of-line loop variation of the in-line ABoK#1059 loop. They are equivalent topologically, but also very similar geometrically.
This is not a knot.

  Here is another loop,

  A very complex ( based on a "double"= "8"-shaped crossing-knot ) nipping structure, and a very simple ( "Myrtle" ) collar structure - I would prefer the exact opposite !  :) Personally, I do not characterize the single-collar bowlines as "secure bowlines", however convoluted their nipping structure may be - even in cases where they are very stable, tight and secure structures, as in the loop presented recently by Alpineer (1). In my mind, a "secure bowline" ( or a secure bowline-like loop ) has to be as easy to untie as the common bowline, and as secure as the fig,8 loop - and the fig.8 loop is a double-collar loop !

Hi All,
        The first photo just a superficial loop, but I like the nipping structure, and I found few more home for the tail.
        Thanks again Xarax.             
         謝謝  alan lee

Hi All,
        I have two more loops here.
        Anyway Xarax have a lots of this kind of loops, but all the knots are dressed tied , I don't want to spend any more of my valuable
        time try to figure out what are these knots.
       
         謝謝  alan lee

   Just for the record : What I had to read then, five years ago, when I dared to publish pictures of some similar knots in this Forum:
 
   Bulloney:  most if not all of these late-blooming so-called "bowlines" are lacking the quintessential element of a bowline -- viz., the central nipping loop, one end being the SPart, the other an eye leg.
   The world doesn't need such lame naming that every eyeknot that someone dreams up garners "bowline" in its moniker as some sort of claim to legitimacy.

   ( Why I believed that I should reply to such ..., I can not understand...)
------------------------------------------------------------------------------------
   However, I had published some better pictures than the ones you had gathered in your previous post, Alan !  :)
   See the attached pictures, and :

Hi All,
        Thanks for the photos and links, make it easier for me to compare your loops with my.       
        The first photo is your loop. since your loop have some similar look with Water bowline,
        Why not give them a load test, after the heavy loading on both of them, Xarax s Pretzel bowline
        holding it rock solid form, but the second collar of Water bowline was separated apart.
        and both of them are easy to untie.

        謝謝  alan lee

  Hi All,
          Simple load test on Xarax s Pretzel bowline and Water bowline.

          謝謝  alan lee

Hi All,
         Just a second thought, why not make it little more complicated, and little more secure.

         謝謝  alan lee

  As I had said to Alpineer (1), I do not like sharp U turns, even in first curves of the returning/second eyelegs...
  It may well be just a prejudice : other people believe they are beneficial to the "locking" of the collar structure.
  " The hard turn... helps to prevent that from feeding material into and so loosening the knot. The coil compresses tightly, for slack security ".

Nor do some ropes --i.p., hard-laid ropes, old stiff ropes,
built-to-be-tough caving ropes.  In which case, one must
go to Plan B!

Hi Alan (Alan Lee),

I just want to personally thank you for your incredible work and contribution to our collective knowledge bank :)

I think you are an unacknowledged genius!

I will photograph some of your fantastic creations as soon as possible in high resolution format.

I am already using some of them on a regular basis...

Sincerely,

Mark Gommers
