Damascus steel is formed with hundreds of layers of iron and steel. These layers are forged together to produce a high carbon blade with distinctively individual patterns. The art of Damascus steel making goes back thousands of years, and no one is certain of it's origin.
It is a powdered metal technology similar to the original damascus (which was first called Wootz steel) from India. Original Wootz had the "damascus" look but wasn't forge welded in many layers like damascus today. It is this Wootz steel that was responsable for many of the "damascus" legends. The "pattern welded" damascus made today is an attempt to reproduce the look of Wootz steel by a different method. SKM damascus is powdered metal, and not just regular steel acid etched to "look" like damascus.
