I have met, by pure chance, the bend
lR - uL first, and, elaborating on it a little, the
oSE,lR-oSE,uL , later. ( The "B" and the "A" knots, respectably, as named initially in the first posts of this thread )(*). It was only much later that, by "reverse enguineering", I have learnt the general method of tying them, and I have met the 5 other new knots belonging in the same tying group.
Now, we can group those 7 knots in
three broad categories. In the
second we can place the Ashley-bend-like (looking) bends (
C-C,
oSE,C-oSE,C ,
oSE,uR-oSE,lL ) In the
first, besides my favourite, also the
R-L (see attached pictures) (**). This bend is also looking central symmetric from each side (but the two sides are not themelves identical, like in my favourite...
)
It might well be proved that this bend will be an equally secure and usefull bend, as the
lR-uL. Its strands are secured, by friction, along an equally convoluted and long path inside the knot s nub. So, the
not-uninterested, or
not-disinterested reader
, is kindly requested to have a look at this bend as well.
A Note. Presenting those pictures, I try to do many things, so I have to compromise a little on all. The bends are not tightened as tight as they could, so the knot retains a more symmetric pre-loaded shape, and the paths of the rope strands are easily followed by sight. A mixture of a realistic image with a diagramm, in short, no one of them being perfect...
(*) P.S. 2011-10-31 : The bend
IR - uL is identical with the B 25 bend, named "Illusion", by Roger E. Miles : Symmetric bends. (How to Join Two Lengths of Cord), 1995. (p. 94, p.113)
(**) P.S. 2011-10-30 : The bend
R - L is identical with the B 24 bend, named "Rhomb bend", by Roger E. Miles : Symmetric bends. (How to Join Two Lengths of Cord), 1995. (p. 94, p.113). See also D. Mandeville, Knotting Matters 29, 1989, 6-13.
