Pattern-welded
Pattern welding is the practice in sword and knife making of forming a blade of several metal pieces of differing composition that are forge welding, forge-welded together and twisted and manipulated to form a pattern. Often mistakenly called Damascus steel, blades forged in this manner often display bands of slightly different patterning along their entire length. These bands can be highlighted for cosmetic purposes by proper polishing or acid industrial etching, etching. Pattern welding was an outgrowth of laminated steel blade, laminated or piled steel, a similar technique used to combine steels of different carbon contents, providing a desired mix of hardness and toughness. Although modern steelmaking processes negate the need to blend different steels, pattern welded steel is still used by custom knifemakers for the cosmetic effects it produces. History Pattern welding developed out of the necessarily complex process of making blades that were both hardness, hard and tough ...

Damascus Steel
Damascus steel was the forged steel of the blades of swords smithed in the Near East from ingots of Wootz steel either 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. History Origins The origin of the name "Damascus Steel" is contentious: the Islamic scholars al-Kindi (full name Abu Ya'qub ibn Ishaq al-K ...
