Locked Double Prusik
« Reply #45 on: July 03, 2014, 07:27:18 PM »
   I believe that most real(tm) knot tyers would sacrifice some ropelength, to tie a more convoluted but simpler, conceptually, knot, even if this might look as an overkill. So I think that, instead of tying the 6-wrap Double Cow hitch shown at (1), to avoid any thinking on how he should arrange the wraps along the pole, one should better make just another step, and tie the 8-wrap one instead. To the devoted believers, I would reply that, yes, it is nothing but a double Prusik  :) - but a locked one ! So, if the Prusik appears tight to them, they should tie, try and see what this beast is able to do, when it will be properly tensioned.
   "Properly tensioned" here, means only that one should tighten the wraps following the method I had described : by pulling each end at a time, the one after the other. I have seen that this hitch continues to shrink, even after I had been pulling the one end after the other for 10 times ( each !  :))( After that, my back refuses to serve my curiosity...)   
   I have only tied it around rather slippery poles and on rather slippery ropes, so I suspect that, on most "ordinary" situations, where the friction forces between the rope and the pole, on the one hand, and between the adjacent wraps, on the other, is much stronger, it would be quite difficult to tighten it very much - but then, in such circumstances, the Double Cow hitch would be adequate, I think.

"... the Single and Double Locked Cow hitches and the TackleClamp hitch ( which can be considered as two Single Cow hitches joined in an anti-symmetric way, i.e., as opposed to the symmetric way they are joined in the case of the Double Cow hitch )."

   Strictly speaking, the antisymmetric way two Single Cow hitches are joined together generates the knot shown in the attached picture - which is different from the TacleClamp hitch. However, this knot is not so stable, and its locking mechanism does not work so efficiently, due to the oblique ( = not "right" ) angle the short segment which connects the two Cow hitches ( the "stop trigger" of the mechanism ) immobilizes the ends by passing "under" them.   
This is not a knot.
