Damascus steel
Damascus steel is the forged steel of the blades of swords smithed in the Near East from ingots of carbon steel imported from Southern India or made in production centres in Sri Lanka or Khorasan, Iran. These swords are characterized by distinctive patterns of banding and mottling reminiscent of flowing water, sometimes in a "ladder" or "rose" pattern. Such blades were reputed to be tough, resistant to shattering, and capable of being honed to a sharp, resilient edge.
Wootz (Indian), Pulad (Persian), Fuladh (Arabic), Bulat (Russian) and Bintie (Chinese) are all names for historical ultra-high carbon crucible steel typified by carbide segregation. "Wootz" is an erroneous transliteration of "utsa" or "fountain" in Sanskrit; however, since 1794, it has been the primary word used to refer to historical hypereutectoid crucible steel. The term "Damascus steel" itself likely traces its roots to the medieval city of Damascus, Syria.
