Ah yes, one can never carry too many left hand threaded, "well-nut doo-hikkies" or the 21st century equivalent of the number 8 fencing wire - the humble cable tie - in all its varied glory. I wonder what happened to the original patent holder of the cable tie.
It's interesting though, some of the very simple plastic moulded parts that we take for granted have an enormous technological production requirement from precise design, production of raw materials then on to actual commercial levels of production. An image springs to mind of this massive cone shaped vat of fuming ingredients and technology and out pops a tiny, pristine do-hicky of unutterable intent which can only be used as an essential element of some other equally technologically dependent machinery.
I like do-hickys and cable ties - they're so "simple"
