Fingernails in different conditions. After the close up of the nail file, here the details of the aftermath.

Images are taken from a point of view as if pointing a finger towards your face and looking at the edge of the nail. The worn fingernail has a round profile and smooth surface, there are no distinct edges. The cut fingernail has a quite pronounced edge and flat surface. The filed nail has a round profile as well, but not a smooth surface like the worn nail. The second picture is a close-up of the cut fingernail surface and reveals the small parts, almost bristles, sticking up. Those are probably responsible for freshly cut fingernails catching fibers of clothing until they are worn down.
