Can someone explain the difference please? Or is there a difference...? Im sure this won't start a war. 
I had a customer wanting a damascus knife so he sent me some cheap stuff off amazon, It heat treated fine and was okay to work with. But I have another piece and dont want to lie to my customers when I make another knife calling it damascus when it may be "pattern welded" and just a rip off.
I watched a video by walter sorrells saying damascus can be used to describe any pattern welded steel. So am I just over thinking this?
