My understanding of true Damascus steel is that it's likely two different crystaline structures, one more ductile (so it can compress to absorb more energy without failing) and the other more brittle (which can hold a sharper edge).y understanding of true Damascus steel is that it's likely two different crystaline structures, one more ductile (so it can compress to absorb more energy without failing) and the other more brittle (which can hold a sharper edge).
In 1806 J.Jones was granted a British patent for the production of gun barrels using iron from horse shoe nails and steel from coach springs. The Damascus barrels were made by layering anything from 8 to 24 pieces of alternating strips of iron and steel and forging them together. These strips were then twisted into a spiral and used to make a 3 or 4 piece plait.
