Damascus has an aggressive cutting quality. It's because the layers meet at the edge and create a microscopic serrated edge.
Damascus is labor intensive which means it costs more in most cases. When made and heat treated correctly, it is awesome, not not only to look at but in the way it cuts and holds an edge.
