Sometimes my flatware leaves grey streaks in butter. I've only seen this with knives in cold butter. They claim to be stainless steel which I would think wouldn't do this. If I recall they were the very best flatware Target had to offer ;) Is something leaching into my food?

    Might this be a knife shaped object made of aluminium, that has been bin the dishwasher? Commented Mar 1, 2018 at 20:38
  • It could be (black) rust. Which means you put it in the dishwasher way too dirty. Or it sat dirty in the sink for a month...

The photo suggests you are using a knife that has serrations. Dirt can get trapped between the serrations. This is not likely to be metal from the knife, but the dirt.

    I'd wager its a bit of char from a piece of toast, jammed up in the serration.
