Meet the Extrema Ratio NK3 Stonewashed Neck Knife, the ultimate tool for those who demand reliability, versatility, and uncompromising craftsmanship in every cut. Born in the heart of Italy, this compact powerhouse features a Bohler N690 stainless steel tanto blade with a tough stonewash finish that resists corrosion, minimizes glare, and reveals a rugged, battle-ready character. At just 6 inches overall and weighing a mere 2.7 ounces, the NK3 slips comfortably beneath your shirt or hangs discreetly at your neck, always ready to deploy.
Every inch of the NK3 is engineered for performance. The one-piece stainless steel handle delivers rock-solid strength under pressure, while its 0.25-inch thickness provides a confident grip without unnecessary bulk. A precision-machined blood-groove not only lightens the blade but also prevents suction when slicing through tough materials. At the handle’s end, a generous retention ring secures your grip in wet or gloved conditions and doubles as a point for quick-release tethering.
Securing the NK3 is Extrema Ratio’s custom-fit Kydex sheath, molded to cradle the blade in silent, rattle-free confidence. Wear it around your neck for immediate access or swap in optional accessories—sold separately—for belt carry, concealed under-shirt concealment, or a modular MOLLE setup on your pack or vest. No matter the mission, the NK3 integrates seamlessly with your gear.
Whether you’re a tactical professional, a hunting enthusiast, or an outdoor adventurer, the Extrema Ratio NK3 delivers precision cutting, effortless deployment, and ultra-compact convenience. Every blade is hardened to 60 HRC, ensuring enduring edge retention through repeated use. And with its sleek stonewash finish and Italian heritage, the NK3 is as much a statement of personal style as it is a precision tool.
Experience the perfect balance of agility and strength. The Extrema Ratio NK3 Stonewashed Neck Knife: engineered for those who refuse to compromise.
