SHOP CASE KNIVESThe Half Face Blades Extremis MK1 Armor Black is a fixed blade knife that effortlessly blends cutting-edge materials with rugged, battle-ready design.

Crafted with purpose and built in the USA, this knife is ready for action whether you're in the wild, on duty, or simply looking to add a standout piece to your collection.
At the heart of this knife is a 3.5-inch plain edge recurve drop point blade made from premium CPM S45VN stainless steel. Known for its superb edge retention and impressive toughness, S45VN offers enhanced corrosion resistance and excellent wear performance, making it an ideal steel for heavy use. The recurve design gives you greater slicing power and cutting leverage, while the drop point provides precise control for detailed tasks. Whether you're cutting rope, prepping kindling, or tackling tactical challenges, this blade won’t let you down.
Finished in a sleek and durable Armor Black Cerakote, the blade resists wear and reduces glare, all while adding an aggressive, stealth-ready aesthetic. The full tang construction adds extra strength and control, giving you the confidence to put this knife through whatever comes your way.
The handle is where the Extremis MK1 truly shines in both form and function. Featuring a black burlap Micarta Iron Grip handle, it offers a secure, slip-resistant grip even in wet or muddy conditions. Micarta has long been favored for its durability and comfort, and the burlap texture adds a tactile surface that enhances control without sacrificing style. Allen bolts keep the handle scales tight and secure, while a hollow lanyard hole adds customization options for carry or retention.
Measuring 7.5 inches overall with a .14-inch blade thickness, the Extremis MK1 is compact enough for everyday carry while still delivering serious performance. Its fixed blade format ensures reliability under pressure, and the included black Kydex sheath with a belt clip provides quick access and secure retention. Whether you're strapping it to your pack, your belt, or your gear, you'll know it's there when you need it—and out of the way when you don’t.
Proudly American-made, this knife is built with care, precision, and a commitment to quality that reflects Half Face Blades’ reputation for excellence.
