Classic 4000 folding knife - Damascus Brand/Manufacturer: Viper DAMASCUS STEEL: a long history of iron, fire and manufacturing skills. Damascus shear steel is made by forging a steel block, bringing it to incandescence and beating it, folding it and beating it again until the steel is layered. The Damascus steelworking technique is used especially by Japanese master craftsmen to manufacture katanas. This technique dates back to the Middle Ages. The first ones to manufacture layered steel blades were the Umayyad Arabs during our Middle Ages. However, they had previously learned such techniques from India. This knife comes with warranty certificate and original wooden case. This knife comes from my father's precious collection in his home. Limited edition of 500 pieces, this one is number 410. This piece also has engravings on the blade - see photos. Wooden handle. Professional shipping. I will provide the tracking code as soon as I ship the parcel (DHL, Nexive, UPS).
