The Boker 110084DAM Leopard Damascus I, is forged out of the German battle tank Leopard I. This specialty steel is not available to the market because it was only used for the military. Our Damascus forger was fortunate to acquire some for Boker exclusively. A chromium-manganese and vanadium tool steel alloy was added to this extremely wear-resistant barrel steel. The result is a remarkably high hardness for Damascus steel (60-61 degrees HRC). The pattern provided on the 300-layer blade is labeled “Small Pyramid.” Handle material is 6061-T6 aluminum and features Ziracote wood inlays. Includes certificate of authenticity and gift box. Serialized. Blade length: 3 3/8 in. Overall length: 7 3/8 in. Weight: 4.4 oz. This Boker knife isn’t just for cutting, it’s for leaving a mark. Limited lifetime warranty. A chestnut tree is the world famous trademark of the Boker knife manufactory in Solingen, Germany. It represents innovative, high quality, exceptional knives, manufactured with pride, by hand, for over 145 years.
