Damascus Lockback Pocket Knife with Peruvian Pink Opal A masterful marriage of fine steel with natural materials! Perfectly functional and collectible, the popular 3" Pocket Knife is accented with pink opal from the Peruvian Andes, whose natural voids are filled and stabilized with a matrix of molten bronze metal . The minerals are painstakingly shaped, ground, polished and assembled by artisans in Santa Fe, New Mexico and applied to the factory-new knife. The body is stainless-steel with a titanium bolster and the handle reverse features solid wood. Closed, the knife is 3" long, sized small enough for everyday pockets. Sleek, stylishly sharp, and practical! About the Damascus Blade With a manual lockback mechanism, the knife features damascus steel formed in Japan with a process known as Sanmai Damascus. Unlike common sanmai, this blade features 110 layers of stainless steel with a Rockwell hardness of 59-60 and a high-alloy exterior pattern to create a dramatic appearance with a rust-free finish. Due to the natural abstract variations in the stone, the vein pattern and color tone may vary slightly. The reverse side features dark, natural wood. blade size: 2.2" handle length: 3.1" overall length: 5.25" (when open) weight: 3 oz. materials: stainless steel, titanium, Peruvian opal, bronze, wood
