yeah, that's insane. i used to work in a pretty regulated industry and they would have all the calibrations done by the metrology department and every instrument would be tagged and made sure to be in compliance. you don't need some wrench manufacturer telling you to calibrate.

how does this help some guy in a shop somewhere that doesn't need strict calibration schedules and bought the wrench secondhand or even firsthand?

I’m pretty sure the main thread here about limited twists is a joke.

In saying that, there were devices with similar restrictions before any IoT existed. Smoke alarms, CO alarms, breathalysers are all devices I’ve seen with enforced lifetime and/or usage counts.
