The art of forging Damascus steel is 2500 years old: two different types of steel are forged, in numerous, alternating, paper-thin layers, so tightly together, resulting in an end product with new, outstanding qualities and an increased bending resistance and breaking strength. Characteristic of the Damascus steel is the so-called ‘Water effect,’ the high-quality, almost symmetrical gradients on the steel, which are the remaining signatures left over from the original materials now melted together. They are produced by the blacksmith, but were first made visible as the ancient guild of the Damascenes ‘extracted’ the blade: only after their processing of the material did the steel reveal the beauty of its inner structure. One of the few blacksmiths, who have preserved this art into the present, is Peter Stienen. For the cutler company, ‘Böker,’ in Solingen he forges every year a couple hundred Damascus-Steel-Knives. Under the continuous use of fire (1,500° C), power and blacksmithing, the materials combine together into 300 layers to create a blade with 3.7 mm strength.
