End grain of a piece of 90 layer damascus. People sometimes think that damascus layers run nicely in parallel. And if you use biased drawing dies and take care to not distort the cross section too much, that may be the case.
This billet however was squeezed and re-squared very aggressively using flat dies. 15 layers became 45 became 90. As you can see, the aggressive squeezing really distorted the layers.
