Prob case by case. I know some Takadas show banding and some don't. I've seen some Kono Tetsujins that show banding even though they aren't etched (but most don't). Myojin said it took a lot of experimentation for the banding on the Tetsujin, so I think there may be some extra steps/changes in the way they're forged. There are some threads on here about controlling banding as well with some comments from makers (here's some comments from Kipp Alloy Banding aka steel segregation?). It is also possible that MFs are specifically selected for banding activity, and the rest becomes kasumis, much like how computer chips are binned.Can you get the same "banding" on Kono Tetsujin? Seems like they are the same.
