Brass? Who said anything about brass?

Typical keys are made from nickel plated hardened steel and nickelsilver. Considering the shiny coating is long gone and the keys are ferromagnetic, I assume it's the first. The keys are certainly hard enough to scrape my glass ceramic stove.

And reports online say that gorilla glass victus is the mist scratch prone gorilla glass, scratching at or around 6 already :/
