Thread: Suminagashi layering?

I'm thinking that the etch on that razor does look like a coffee etch. One good thing about the coffee etch is that it is much milder and the edge protection should be less important.

That does sound like a good idea.

Thinking about this a bit more. I would expect that most makers using sumagashi steel blades are using material removal and not forging due to the construction of the laminate, so scraps should be plentiful. Also due to the alloys used, it will etch differently than typical 15n20/carbon steel PWS.
