Half Face Blades Extremis MK1 Fixed Blade Gray G10 Textured Grip Acid Splash Blade HFEXTRGY

The Half Face Blades Extremis MK1 is a compact fixed blade engineered for control, reliability, and hard-use performance in a streamlined, mission-ready design. Built in the USA with premium materials and precise craftsmanship, this knife is made for users who demand a dependable tool that carries light but performs heavy. Whether it’s on the belt, in a pack, or part of a dedicated field kit, the Extremis MK1 delivers consistent cutting power without unnecessary bulk.

At the core of the knife is a 3.5-inch blade crafted from CPM S45VN American steel. This modern stainless steel is known for its excellent corrosion resistance, strong edge retention, and balanced toughness, making it a trusted choice for demanding environments where reliability matters most. At .14 inches thick, the blade provides a confident, durable profile while still maintaining the slicing efficiency and precision needed for detailed cutting work and everyday utility tasks.

The blade features an acid splash finish that gives it a rugged, irregular pattern with a dark, weathered character. Beyond its aggressive visual appeal, the finish helps reduce glare and mask wear from extended use, ensuring the blade maintains a field-ready appearance even after heavy work in harsh conditions.

The handle is constructed from gray G10, a high-strength composite material valued for its durability, 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, giving you a confident hold whether your hands are wet, dry, or gloved. A hollow lanyard hole adds functional versatility, allowing for additional retention options or customized carry setups depending on the user’s needs.

Measuring 7.5 inches overall, the Extremis MK1 strikes an ideal balance between compact portability and usable cutting length. Its ergonomic handle design supports natural indexing and comfortable extended use, while full tang construction ensures maximum strength from tip to pommel. This is a knife built to perform without compromise when conditions get demanding.

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