Egg piercer?
I think every German kitchen in the 70s or 80s had one of these.
A doorbell for anti-vaxxers
I expected a doorbell one. Nice twist.
Pricking a hole in an egg before boiling. My mother had one exactly the same.
I use it after boiling to pierce the membrane. Makes peeling easy.

Sounding device

What is a sounding device? It's clearly not a hearing aid...
Tiny dented German WW1 helmet, or what the front desk person does to the bell after people ring it too goddamn many times
You really don’t know what this is?
It is a (arguably fancy) egg piercer for boiling eggs.
Challenges are known by the poster. It's a game.
Citrus peel scorer?
Edit: Nope.
