Yeah, those were different times.

On one of my first flights alone, 16-year-old me had forgotten I had a knife in my backpack. X-ray guy took it with him to a back room, measured the blade to be shorter than, idk, 12 cm or so, and just handed it back.

Another time I found a long wood screw on the floor at school, and out of boredom during class, I just drove it sideways into my boot's heel. Months later it gave the metal detector guys at the airport a bit of a pause. They asked me to remove the boots, x-rayed them, came together to admire my long-forgotten idle work, scratched their heads and had me proceed.
