What is Damascus Steel?
According to Oxford Language Dictionary
Damascus Steel made with a wavy surface pattern produced by hammer-welding strips of steel and iron followed by repeated heating and forging, used chiefly for knife and sword blades. Such items were often marketed, but not necessarily made, in Damascus during the medieval period.
According to Wikipedia
Damascus steel was the forged steel of the blades of swords smithed in the Near East from ingots of Wootz steel[1] either imported from Southern India or made in production centres in Sri Lanka,[2] or Khorasan, Iran.[3] 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.[4
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.
