This is something I have been working on since I got my power hammer. I wanted to make some damascus with more complexity. I discussed it with Mike Blue and he gave me some tips.
The damascus is a laminate that was crushed orthogonally to the initial layers and restacked several times. Then I made a san mai with a piece of O2 in the middle, and then twisted everything.
