Photos Nickel silver patina...?

I just observed a couple of days before that the knives in my traditional collection have some roundish small spots on the bolsters, maybe similar to those found on brass?
Some have them more pronounced, some have more on some bolsters, while some only have many on one bolster. It's not a problem, can only be spotted right with a magnifying glass, otherwise they look like small points on the finish.
But I'm just curious, have you encountered this, and if so, what is it? A tarnish perhaps, as those were just staying there?
I took some pics, but it's hard to capture them. That knife is a peanut, so actually pretty small.

Yep, I think all of my knives with ns probably do In some capacity.

Nickel silver is a type of brass. It can and will patina/tarnish. It's polished easily though.

Yeah, I know, haven't noticed so far, because I've been carried my peanut, and sometimes my stockman, and they were fine. After buying a few more, and those just stay around in a box, I noticed these marks on some of them.
Might as well take them out for a spin
Thank you.
