Dark Ops love to brag about working with top Navy SEALS to design their knives, and they certainly deserve to be proud of the rough-and-tough tactical knives that they've come up with. All of their knives are made from a proprietary hybrid alloy of Chromium, Cobalt, Tungsten, Vanadium and Molybdenum with surgical grade stainless steel. Thanks to that unique blend of metals, their blades are capable to surgical steel-like sharpness without being hampered by the brittleness that is common for hard steels. These knives are made by and for true warriors. Dark Ops knives have saved many a life, so we want to make sure that you get the one that works best for you. That's why every one of their knives is backed by our unbeatable 60-day money-back guarantee.
