Is the threaded part metallic, composite or carbon? Using an alloy insert wouldn’t be difficult, so it’s an odd choice to use threaded tow-based discontinuous composite (aka ‘forged’ carbon fibre) for a threaded safety critical part, but it can be made quite strong. 🤷♂️
Quite a few calipers operate(d) on a similar principle, with duly mashed cables as a result. Not an elegant solution, at least.

A long sleeve 50 UPF surfing shirt. I did get it 5 or 6 years ago, so it’s done it’s time. I took it to Greece recently, got burnt, looked online and saw that they don’t last forever. Putting 2 + 2 together I think that the sun marks on my shoulders have probably been caused by the last few times I’ve been in full blown tropical sun erroneously thinking I was protected.

The Stone Age persisted for roughly 3.4 million years, but it took barely a couple of thousand years to 'find' Iron.
Good point, but as a counterpoint: metallurgy ‘developed’ on seemingly isolated parts of the globe (at around the same time). It’s an entirely plausible coincidence, but a hefty one, that Native American tribes created the first copper tools ever at around the same time that Middle Eastern tribes did, and no one had ever done something similar before.

Agreed, but our understanding of the chronology of human achievement is limited by what has survived through the ages. Prehistoric does not mean rudimentary: Göbelki Tepi predates Stonehenge by 5000 years. More time passed between the time that site was active and flourishing and the construction of Stonehenge than between Stonehenge and now, and we have no idea who built (the much more complex) gobelki tepi or how or why.
