I'm reminded of how blacksmiths use instant coffee to stain damascus steel, at least the ones on YouTube
Does that last long? Commercial damascus is typically acid etched which seems like it would last better, but it wears off eventually too.
[edit] oh, I guess coffee is acidic, so maybe it’s not that different. I was thinking of using it as a stain at first
