L6 like 15N20 has enough nickel to show up in Damascus whereas 8670 doesn't. Have you made any Damascus with a saw blade and it shines when etched JM?
Maybe I should reword that, does the blade steel make a shiny layer?

It stands out as much as 52100, makes 15n20 pale in comparison. Now I will say I haven't tried any Damascus with this last batch. The source was a tree trimming company, one of those pole trimmers. I've used it to make some knives and a couple of hawks. Planning on welding up a billet in the future though.
