Well I had not realized that there was a carbon and stainless type of Damascus. In reality I was thinking that the darker layers would stay the same color or be the dark color (blueish or purplish) and the lighter layers would show off more of the random swirl patterns. As for the use I was thinking about the slide of a 1911 style pistol. It sounds like it might not be as feasible as I had thought it would be.
If you have to explain how great the idea was - it wasn't.
