Mystery object

This thing has been bothering me since it appeared among a bunch of stuff in my parents' apartment and I'm afraid my daughter will find it among my possessions and be driven crazy, too. If I find out what the hell it's for, I will label it.
It appears to be made of silver. The studs are fixed; one is pointed, the other rounded. That's all what I can tell you.
I have faith that one of you will recognize it or figure it out.
