Half Face Blades Extremis MK1 Fixed Blade Black G10 Textured Grip Acid Etch Blade HFEXTRBKG10

The Half Face Blades Extremis MK1 is a compact, mission-ready fixed blade built for dependable performance, clean handling, and rugged American craftsmanship. Designed with a focus on versatility and control, this knife delivers serious capability in a streamlined platform that excels in field use, tactical applications, and everyday utility. It’s the kind of blade that disappears until you need it—and performs without hesitation when you do.

At the core of the Extremis MK1 is a 3.5-inch blade crafted from CPM S45VN American steel. This premium stainless steel is known for its excellent corrosion resistance, strong edge retention, and balanced toughness, making it a trusted choice for real-world use in demanding environments. At .14 inches thick, the blade offers a confident, durable profile while still maintaining the slicing efficiency and precision needed for controlled cutting tasks.

The blade features an acid etch finish that gives it a dark, subdued appearance with a hardened, broken-in character. Beyond aesthetics, the finish helps reduce glare and conceal wear from hard use, allowing the knife to maintain its field-ready look even after extensive use in harsh conditions.

The handle is built from black G10, a high-performance material valued for its strength, stability, and resistance to moisture and temperature extremes. Secured with rugged Allen bolts, the construction is clean, solid, and purpose-driven. The textured grip enhances traction and control, ensuring a secure hold whether conditions are wet, dry, or gloved. A hollow lanyard hole adds functional versatility, giving users additional carry or retention options depending on mission needs or personal preference.

Measuring 7.5 inches overall, the Extremis MK1 offers an ideal balance between compact carry and usable cutting length. Its ergonomic handle geometry supports natural indexing and reduces fatigue during extended use, while full tang construction ensures maximum strength and durability from tip to pommel. This is a knife designed to stay reliable under pressure and consistent through hard use.

A precision-molded Kydex sheath is included for secure retention and flexible carry options. Whether mounted on a belt, integrated into gear, or carried discreetly, it keeps the knife protected and immediately accessible.
