The Best Kind of Everyday Engineering
To be honest, safety pins are an incredible functional design turn. They’re inexpensive, straightforward and somehow batshit useful. From fashion fixes and first aid to D.I.Y. projects and diaper duty (hello, vintage cloth diapers), they’ve weathered the test of time. And that’s in part thanks to the sort of small design details like those in a hole in a safety pin. It’s one of those “you don’t see it until you really see it” type of things.
Makes you think about how many more common tools have hidden features we never knew about, right? Like the hole in the pot handle (yup, that’s for your spoon), or that little groove you see at the bottom of plastic bottles (pressure control!). Engineering is truly lowkey amazing.
