Yea, now I know what you're talking about with carbon migration, that line I see sometimes with San Mai - after all, 410/416 SS is very low carbon. The layer of SS cladding being too thin is what I was thinking, I'd not thought about carbon migration from the HC to the SS cladding, and with it thin it would allow some dark etching. My San Mai for hunting knifes works just fine since they're usually >1/8" thickness. It's kitchen knives where I have the problem since I like thin blades there, well less than 1/8", more like .070 to .090" thick and that doesn't leave much room for cladding with a .040" core.
Putting a layer of copper between the cladding and core works good, but with .020" copper on both sides, then .040" core, that's .080" right there before it's "squished" down with press.
