Crossing knot based loops(new?or new virtual pseudo bowlines?)
« on: February 07, 2019, 11:53:44 PM »
When i first tied this loopknot, i was not sure if it qualifies as a bowline.The returning WE does not pass through the loop that first came in,(photo 1) but through the loop next to it.I am not really sure if this structure fits in the virtual (pseudo) bowline category, but one thing is certain, that there is a crossing knot nipping structure.

When i saw Mike Sweeney's pseudo bowline, i realised that both knots share some resemblance up to a certain point.The difference is that this loopknot has an extra tuck to the left(photo 1),which provides an interesting lock,enhancing safety and it is not created with the adjustable technique Mike Sweeney is presenting in his video, which is quite interesting, but with a rather straight forward method.

There are a few ways to turn these knots TIB, with the cost of extra complexity(extra maneuver) and photo 3 illustrates such an approach.The WE dives through the loop next to it and comes back under itself,exiting parallel with the SE through the collar.This TIB knot belongs to the category of knots where the first line of defence is weaker than the second line(the collar).I am not sure if this is a disadvantage and i would care for a second opinion about this approach.However, i am working with structures that have stronger first line of defence than the second line(collar), which prevents segments of rope to remain loose during heavy loading.

These knots shown here,have their mirrors if someone  starts the tying process with a different crossing knot(mirror of the one being used here) and follow similar steps!!!!

Actually, no : the characteristic of the crossing knot
IMO is that it collars itself; this knot doesn't.

I don't like how all the knotting is without help to the
rather sharply bend SPart, which turns around the
(mere) two diameters more as though they are in
line and just one at the turn apex.  There are some
ways to put another tuck through here.  But, then,
there are other knots that do this ... .


Thanks,

I think you have a point there Dan, meaning that this is not the classic shaped-8 crossing knot, which is immediately recognisable.However, i believe this is another crossing knot where the SE divide the nipping structure in two sub-loops and collars the eye leg of this very nipping component.On the other hand,the knotting of this simple collar structure and the sub-nipping loops,works pretty well by my opinion as a stabilization and constriction factor of the whole structure, as compared with other classic approaches shown in the photos below.
Such simple easy to tie knots, deserve further investigation and there are indeed a few tucks that could also work well here.
For comparison reasons, a virtual TIB bowline with a yosemite finish(or a figure eight collar structure) is shown in the following photos where the WE returns through the same nipping loop that it first came in and comes back through the collar with a yosemite tie off.
I believe this has been tied by other people before, i have just added a yosemite touch.

"Crossing knot" to me is the structure in which the
material crosses over (e.g.) an object,
turns back around it to then turn over itself,
and then goes out now UNDER the object
and beyond; if making an eye knot, it would
return so to give substance to the (what would
have been imagined/anticipated) object *crossed*.
And, so, the SPart bears strongly into the turn
over itself.
This knot doesn't have this structure.

Xarax has presented a plethora of such things,
here:  https://igkt.net/sm/index.php?topic=3467.0
--including some in reverse orientation to what
I verbally sketch above.
