The Extrema Ratio BFK Zero in black is a compact folding knife that carries the BFK family's tough tanto design in a pocket-friendly format. The 2.63" flat ground tanto blade is Bohler N680 stainless with a black MIL-C-13924 burnished finish -- N680 is a high-nitrogen Austrian steel famous for outstanding corrosion resistance, popular in marine and dive knives, and the military-spec black finish cuts glare. The tanto profile gives a reinforced tip for piercing and durability. The black anodized aluminum handle keeps the knife light and sleek, at 4" closed. A thumb pull allows one-handed opening, and a pocket clip is included.
