The Cachet Bend

The Cachet Bend
Theory;
Rarely we see a half knot securing a bend for the best effect.
It's the case here.
Strangely the half knot is put in place before the 2 loops structure.
In the end it will serve as a "cachet" to close and squeeze the final structure.
It seems to me that this knot is easy to untie and resists jamming, to what degre?... further testing will be needed.
As for the slipping record I hope that someone in this forum is able and willing to test it with his dyneema rope.
My second post will show the how to.

How to tie this thing;
I hope the photos are ok.
I succeed in tying the Cachet with a 4lbs fishing line...an exploit I dont want or reitarate.

@xarax
This knot (on the photos with 15mm braides nylon) can be dressed with climbing ropes anytime. Not only with soft ropes. (test done)
The steps leading to the final result are crucial.
This is not a one stage built knot; the tyer must follow exactly the sequence shown from 1 to 5.
"Moreover, I do not see anything indicating that this bend will be able to hold on Dyneema : I believe it is less convoluted than required - but this is only a gut feeling - I have not tied it on this material."
In fact The Cachet Bend a is pretty simple bend using the "ABC" of knot knowledge.
It is an overhand knot crowning an opposed half hitches structure at a 90 degre angle.
The point is; are we able to built something simple and still able to hold on the Dyneema?
That's a challenge :P

I should have put it this way:
Attention Tyers!
Attentive dressing is required.
Steps 2 and 3 (in the how to) are capital.
The upper structure must be placed exactly as shown in order to commit the strangling force of the overhand knot
to its utmost effect.
I joint pics to show the behavior with yellow rope.
I stand correct saying that hard rope can be used, but stay away from this kind of crapy stuff hard to manipulate.
As for the bend itself I think that Clifford would proud of me ;D
