Boker BK-110084DAM Model 84 Leo Damascus. A truly rare and unique piece of work and a must for your collection, blending the centuries-old art of hand forged Damascus with a piece of history. The Leo Damascus, a high performance Damascus steel, was made available to Boker through a noted European Damascus forger, Markus Balbach. The steel used in this knife is forged out of the barrel of the German battle tank Leopard I, thus Leo Damascus. This specialty steel is not available to the market and there is no material number even assigned to it because it was only used by the military. Herr Balbach was fortunate to acquire some for the exclusive use of Boker. 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 (63-65 HRC). A very high performance Damascus. The pattern provided on the blade is labeled small pyramid, providing a spectacular work of art; and as with all true Damascus, every blade is different. Handle material is hard coated 6061-T6 aluminum and features exotic desert ironwoods inlays. Liner locking. Includes certificate of authenticity and gift box. Serialized. Overall length: 7 7/8. Blade length: 3 3/8.
