A nail clipper is a pretty interesting little bit of machinery — the construction, and the principles behind it. It’s very simple, yet it’s also oddly complex. And on a level it seems like some ancient baroque thing. Like some awkward eighteenth century invention, that just happens to work as intended. And on top of that there are some curious concessions to convenience — the complex way the top swivels back around so you can close it flat, and the nail file.

The idea behind it is… a bit odd. Nail scissors aren’t good enough. What we really need is a finger guillotine! No gradual snips here. Just snap ’em off, one quick motion! And the way it achieves this is by a rather simple yet oddly complex lever and spring system, that transfers a huge amount of force to a tiny area. (To make up for the lack of the falling distance, you see.)

It’s such a strange invention.
