The Extrema Ratio BFK in tactical mud is a crossbar lock folding knife that pairs a blacked-out drop point blade with a subdued, field-ready handle. Its 3.25" flat ground blade is Bohler N690 stainless under a black MIL-C-13924 burnished finish, a military-spec black oxide treatment that cuts reflections, over a cobalt-enhanced Austrian steel that sharpens well and stands up to moisture. The drop point shape makes it a true all-rounder for everyday cutting. The tactical mud anodized aluminum handle keeps the knife light and low-key, and the crossbar lock releases easily from either side, in a 4.5" closed package. A thumb pull allows one-handed opening, and a pocket clip is included.
