Is it normal to press my fingernails against a hard surface?

I feel the need to multiple times every day, even more so after I trim my nails. Sometimes just a surface doesn't cut it, and I need a sharp 90° edge. If I can't find anything I'll use my thumbnail or even the edge of one of my front teeth.

    I usually press my fingertips against my palms.. Idk what it is about it but it's kind of calming or relieving in a way. I guess that's similar to what you do. Although I'm not sure if it's normal in either case.
