Why do you think some door handles have two tiny holes?
Here’s the fun part: those holes can be a built-in “signature.” In many older building designs, the latch assembly is tuned so the handle can’t be easily forced without the key measurement fitting the mechanism. The holes act like alignment points for internal parts during manufacturing and maintenance. So it’s not just decoration, it’s a quality-control landmark you can’t see once the door is closed. And yes, people actually forget to look for them. The next time you pass an office or hotel entrance, glance at the handle and find those odd little openings. You might notice patterns that match the brand or era of the lock. It’s like the door is quietly telling you how it was built. Want a second hint? Tell me what kind of handle you see, and I’ll guess the likely lock mechanism style. This one is made for sleuth mode.
