Thanks for your response. My point is that they are both Damascus, Twist and other patterns.
Damascus refers to the process of layering different types of metals together to create a faggot and then heating up this faggot and hammer forging it into a billet or bar.
From the billet or bar you can then make bbls (or swords, knives, etc).
This is how Manfred Sachse explains it in his authoritative text Damascus Steel.
How you create the original faggot of steel, how many billets/bars you use, and how you treat the billet/bar (twist or not) determines the type of Damascus steel created.
At least that is how I read it.
