Extrema Ratio N.K.2 Black Knife
The Extrema Ratio N.K.2 Black Knife injects cutting-edge performance into a compact, ultra-light neck-knife format. With a precise 50 mm tanto blade forged from BöHLER N690 steel hardened to 60 HRC, it slices through tough materials and excels at intricate tasks. This next-generation model elevates the original N.K.1 design, adding a blood-draining slot for reduced friction in deep cuts and a bold tanto tip for piercing strength. A secure handle geometry and integrated finger groove ensure a confident grip and eliminate accidental slips during quick draws or detailed work. The contoured spine accommodates either thumb or index-finger placement, matching your preferred style whether you favor a reverse or standard grip.
Packed with versatility, the N.K.2 performs razor-sharp slashes and delivers precise control for carving, prying, or emergency field repairs. Its rock-solid construction bridges the gap between offensive power and meticulous handiwork, making it an essential everyday-carry or survival companion. The package includes a sleek, rapid-release Kydex sheath featuring a paracord lanyard for comfortable neck carry. It also integrates seamlessly with MOLLE systems, allowing attachment to tactical vests or any Cordura sheath in the Extrema Ratio range. Optional accessories such as the belt-clip and under-shirt concealment system amplify its adaptability for urban or outdoor missions.
Choose from three distinct finishes—stealthy Black, Desert Warfare Tan, or rugged Stone Washed—to match your gear and environment. Every N.K.2 undergoes MIL-C-13924 burnishing, enhancing corrosion resistance and reducing reflectivity in low-light operations. At just 69 grams total weight, it stays nearly invisible until you need it most. Whether you’re an adventurer, first responder, or tactical professional, the N.K.2 delivers uncompromising reliability when seconds count. Embrace the N.K.2 as your trusted sidekick for every challenge ahead—compact, powerful, and ready.
