Foldable knife MF1 EVO D BLACK SATIN M390 - Extrema Ratio

MF1 EVO represents the evolution of the historic MF1 folding knife. This revolution embraces Extrema Ratio's new design philosophy, combining aesthetics and functionality in an innovative way. It is not simply a stylistic reinterpretation, but a refinement of performance, which keeps intact the essence of a tool designed to face the most demanding challenges. With MF1 EVO, the range of colors, blades, and steels available has also been expanded, offering even greater versatility to meet every need.

The handle consists of two finely crafted anodized aluminum scales, to which Extrema Ratio applies a hard oxidation treatment, making the handle more resistant to wear and corrosion. The handle is equipped with a rear glass breaker in hard metal. Two steel frames contribute to increasing the strength of the entire structure, making the MF1 EVO suitable for the most demanding uses.

The reversible steel clip is designed to allow concealed carry in a pocket, making the knife invisible from the outside.

The blade locking mechanism is LINER-LOCK, accompanied by a new generation “HIDDEN LOCK” safety system, which is compact and lightweight and can be operated manually.

For the MF1 EVO D BLACK SATIN M390, MF1 EVO D RED SATIN M390, and MF1 EVO SP BLACK M390 versions, Extrema Ratio uses Böhler M390 steel heat treated to 61 HRC which, thanks to a powder metallurgical production process, guarantees long-lasting cutting efficiency, wear resistance, and oxidation resistance.

The MF1 EVO offers two blade profiles, each suitable for different contexts of use. The drop point blade is ideal for those looking for a versatile and precise knife, particularly suitable for urban and outdoor environments. Its balanced shape and rounded tip make it a good choice for everyday activities, such as cutting light materials or handling small emergencies, ensuring a good compromise between strength and maneuverability.

The spear point blade is particularly suitable for tactical environments where high penetration and robustness are required. Its sharp, central tip makes it ideal for more demanding situations where precision and control are essential for effective operation.
