MF1 EVO represents the evolution of the historic MF1 folding knife. This revolution embraces the new design philosophy of Extrema Ratio, combining aesthetics and functionality in an innovative way. It is not simply a stylistic revisitation, 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 is also expanded, offering even greater versatility to satisfy every need.

The handle is composed of two finely crafted anodized aluminum scales, on which Extrema Ratio applies the hard oxidation treatment, which makes 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 robustness of the entire structure, making MF1 EVO suitable for the most demanding uses.

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

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

MF1 EVO is available in 6 variants with two different types of steel, both supplied by Böhler, an Austrian company with which Extrema Ratio has been collaborating for more than 20 years using its proven materials for the production of its blades.

MF1 EVO D BLACK uses Böhler N690, hardened to 58 HRC for the best balance between edge retention and strength, the type of steel used by Extrema Ratio for most of its knives.
