I like the sure, almost self-complacence

way this rock-solid tight hitch "sits" on the surface of the pole... Although it is not TIB ( as the "similar", yet TIB Bull Clove hitch is ), its perfect symmetry, its tightness and its conceptual simplicity make it an interesting knot. How one can untie this thing ? With great difficulty !

If you plan to tighten it as much as you can, better tie it near one end of the pole, so you can slide it, and pull it out.
The interesting reader will notice that here I have not crossed the lines into the "nipping tube", as I did in the case of the "simple hitch a la Gleipnir" - the Clove "neck", by itself, is so tight, that this precaution ( which, in a sense, transforms the original Gleipnir into a Gleipnir X - X=crossed tails ) is not required. In this knot, I believe it pays more, regarding its tightness and security, to be able to pull its ends more easily ( so, to refrain from twisting them around each other inside the "nipping tube" ), than to increase the friction between them even more, in order to secure their "locking": the Clove hitch "lock", wrapped around compressible, elastic structures, as the ropes are, provides all the security we need - and then some !
