I had tied and tried the

***10 hitch, *and all the other hitches I could derive from the Borromenean rings. No good practical knot emerged. It seems that Mathematical "knots" can rarely, only, serve as an inspiration for Practical knots - because the most important characteristic of the former is topology, while of the later is geometry - and there is no bridge in between those two Lands.

In Practical knots, we start from one of the few geometrical configurations, which is stable

*because* it utilizes the friction of ropes - we do not start from one of the many topological configurations of the Mathematical "knots", which will become stable knot

* if* it utilizes ropes with friction.

Many of the best Practical knots I know are TIB, that is, topologically equivalent to the un-"knot", to the un-"knotted" line. What could emerge if one would had tried to figure out Practical knots starting from the mental image of an unknotted line ?

( Tie the

*Double Cow hitch*, or the

*TackleClamp hitch* shown in the attached pictures, which are based on the implementation of the

*opposing bights locking mechanism*, to see what I mean. )
