Damascus Steel was a tough steel containing molybdenum and having a characteristic wavy pattern on its surface that resembles watermarking. Damascened sword blades, famous for their cutting edges, were made during the Middle Ages at Damascus, Syria.
The origin and method of making Damascus steel are not definitely known. It is thought, however, that alternate layers of steel and iron were hammered together into thin bars, bundled together, reheated, and forged again. The process was probably repeated until the steel and iron were thoroughly worked together.
