Capsized 2:2 Cube bend ( M. B18 )
« on: November 08, 2012, 04:24:25 PM »
  We can simplify the Bowline bend ( ABoK#1455 ), and get something like the B bend, presented at (1).(See the last two attached pictures, for two variations of the B bend ).
  I had not realized to this day that the very simple 2:2 Cube bend ( M. B18), in its capsized form, can also be considered as a Bowline bend or as a B bend - in fact, it is the simplest possible Bowline bend ! :)
 If we see it like this, this bend becomes very easy to remember how to tie, and to tie. ( We have just to pay some attention to dress the knot correctly, because the tails are nipped better if they are not adjacent to the crossing point of the nipping loop they go through. )
  When we set up the bend, if we wish we can pull the ends even more, and dress it in the more compact form of the original 2:2 Cube bend. It is interesting that the Capsized 2:2 Cube bend can be considered as a compound knot, a tensioner/binder, which, when its two links approach each other, it is trasformed onto a bend - an inter-penetrating-overhand-knots bend (2).
  ( Something like this happens in the case of the Capsized Oval bend as well - where, in place of the nipping loops, we have overhand knots (3).)

   The B binder, where the two links of the 2:2 Cube are spread out. The (capstan ?) effect of the 2 collars, the gripping power of the 2 nipping loops, and the mechanical advantage of the 4 connecting segments, all work together and make a surpizingly secure binder.
   Also shown, at the second and third attached pictures, the Cube bend ( M. B18) in its compact ( cubical ) form.
