Many people think of locks as a modern invention, but the first tumbler locks date back to ancient Egypt around 4000 years ago. They were made of wood and used simple pins to secure doors. It’s fascinating how some of the basic principles of locking mechanisms have stood the test of time, even as our tools have become more advanced. What’s the most surprising thing you’ve learned about lock history?
It’s so true that some basics have survived! I recently had to fix an old wooden door lock that used a similar pin mechanism. It was surprisingly easy to get it working again after all these years.
I completely agree that even small lapses can lead to big issues.
, this drives me nuts too! We recently started using a simple calendar alert system for our calibration checks, and it’s made a world of difference — those little reminders really add up. I can’t believe we were letting those slip.
