Hum... Since I've brought a digital caliper that allowed reading sizes with actual 0.01mm precision instead of "guessing it's around X", I've noticed I have no object around that won't compress by something larger than that amount when I apply reasonable amounts of force into the caliper.

I'm also sure it's not calibrated to this level, but that doesn't hurt relative measurements.

That’s why calipers ought to have those tiny “rolls” that you can turn to move them, instead of pushing, this way you can’t “overtension”.

My analog ones do have a push wheel that slips easily.
