Why do humans have finger/toenails? (lemm.ee)

They seem like one more bodily detail to tend to without much benefit, and sometimes more detriment (breaking a nail or scratching oneself up, ouch!).

I remember reading of a special treatment that makes them sturdy like claws. I won't mind that. A multitool made out of your fingernails can be pretty handy.

any source/link on making the nails harder?

I encountered this in some paper encyclopedia as a fun fact and I struggle to google it now, so probably it's BS. I recall people who make world records out of their nail lenght use acryl and oil, but it doesn't seem to help that much. The base of the nail seems to be the weakest part of that scheme, and even a metal claw would probably get torn from the finger under any serious pressure causing more problems that it solves.
