Especially for Böker, Norwegian divers have now retrieved parts of the special armor of the Tirpitz, from the Fjord. These pieces of living history are being exclusively forged by their Damascus forger to an extraordinary Damascus steel with an exciting background. The pattern “Great Pyramids,” with more than 300 layers, adorns the mighty 4” blade, and makes this piece the highlight of any collection. The combination of the Tirpitz steel and carbon tool steels also creates an extremely rugged Damascus steel, which has a hardness of 61° HRC, and can handle any cutting task with ease. The handle, made of high strength AlMgSi1 aluminum (with Silicon, making it a much higher quality than standard AlMg3), is hardcoat anodized and provides a firm and secure grip. The reversible clip allows for tip-up or tip-down carry. For the handle inlay we chose domestic walnut, which has a long history as shaft wood for German rifles due to its superior characteristics. This eye-catching inlay also features the original Tirpitz crest. This knife combines history, tradition and modern technology in a more than unique way, and is handmade in the Böker manufacturing facility in Solingen, Germany. Comes complete in a wooden presentation box with a certificate of authenticity, and is serial numbered. Overall length: 9”. Blade length: 3⅞”. Liner thickness: 1/16”. Weight: 5.9 oz.
