Damascus.
Damascus Steel rings by Lashbrook are made by hand, mimicking ancient metalsmithing techniques originally used to make samurai swords. Using two alternating types of stainless steel, Lashbrook master craftsman heat, bond, twist and fold the metal layers together to produce vivid patterns. After patterning the metal, there can be up to 100 layers in each piece of finished Damascus.
