The Extrema Ratio MF1 EVO D Outdoor G10 Nitrogen folding knife represents a high-performance evolution of pocket blades designed for demanding field operations and rugged outdoor use.

Nitrogen Steel Blade Performance: The Drop Point profile blade is crafted from high-carbon stainless steel enhanced through a specialized nitrogen treatment (Nitrogen Steel). This manufacturing process gives the metal superior edge retention, exceptional corrosion resistance, and a dense molecular structure engineered to withstand heavy mechanical loads.

High-Grip G10 Handle Scales: The anticorodal aluminum frame features 3D-machined G10 handle scales. The aggressive surface texture guarantees a firm, slip-resistant grip under any environmental condition, including wet environments, mud exposure, or while wearing tactical gloves.

Advanced Locking and Safety Mechanisms: Blade deployment is smooth via the ambidextrous thumb stud or flipper mechanism. The main Liner Lock system is paired with a secondary manual safety lock that prevents accidental closure during heavy cutting tasks, providing fixed-blade reliability and user protection.
