Material for weapon blades has to be carefully selected, as a balance between hardness and toughness is required to function properly. In antiquity, the main metal used was copper, then bronze, iron, and finally steel. Prior to the invention of steel, several techniques were developed for reducing the brittleness of iron. Perhaps the most well known is pattern welding, a technique used for katanas (samurai swords) or 'damascus' blades. This was a very labor-intensive technique - and so such swords were very expensive.
