I remember about a decade ago, my grandfather taught me a particular wire "knot". He called it a Cocky's Hitch. I remember the first step was to take a length of thick fencing wire and fold it in half. and the last step was to put a screw driver though the bight, and twist -- wrapping it around the other end and drawing it tight.
But not the intervening steps. Or the fine detail of those steps.
I think we were using it to build a wind break, attaching some tin sheets or thick cloth to some star-pickets.
It could also be used to secure 2 spars to each other in the place of a lashing.
It is very strong. my grandfather told me how back in the day they used to build houses out of it. I suspect they actually build farmsheds with it, and he was telling some stories.
