The MF1 EVO D is a folding knife from Extrema Ratio built around a 3.75-inch Bohler M390 stainless blade finished in satin. The drop point profile and hard stainless steel make it suited to general cutting tasks and outdoor use. The black anodized aluminum handle houses a linerlock mechanism paired with what Extrema Ratio calls their “HIDDEN LOCK” safety system—a new generation design intended to secure the blade during use. Opening is straightforward via the thumb stud. A glass breaker is integrated into the handle for emergency situations, and a pocket clip allows carry in a front pocket or pack. Closed length is 5.25 inches, making it compact enough for EDC without sacrificing blade real estate.
