Karl,
Huge amount of respect for you and your work - always impressive! I've read through a bunch of your posts on other forums and was hoping for your opinion on something.
Tried a blade of 416 stainless and 80crv2 for a stainless san mai project. Followed all the suggestions as best I could, and ended up with a solid blade that made it through heat treat with no cracks and looked good. After cleanup, acid etch I ended up with the pattern shown below. I'm happy with it, but don't see much for a carbon migration line. The welds were solid, everything forge welded well.
Longer soak time before pressing? Other steels work better? Different grind? Other?
Thanks - appreciate your thoughts.
