A pre-emptive slow clap to the first person who responds "It's a hallmark of some kind..."

I did a reverse image search on the two separate elements but got nothing identical in the results.

A heavy (4.5oz) bottle opener that I assumed was steel until I tried (and failed) to hang it off my magnetic knife rack, at which point I took a closer look at it and realised that what I had assumed was a manufacturer's logo wasn't.

You've already had it...

A pre-emptive slow clap.
