Thank you, Gentlemen!
Your replies are what I expected.
I've colored titanium with a torch, but had never tried that method on steel, so I thought I'd reach out first.
I see that Way Of Knife has a stainless heat anodizing service.
I buffed out the center of the pivots, to match the stonewashed blade finish.
I think they look good, so that's where they'll stay.
Should I not like the way they look once the knife is reassembled, I'll contact WOF to see what the cost would be to make the pivots bronze.
Once again, thanks for weighing in, it's appreciated.
Stay safe.
