Extrema Ratio BFK ZERO Compact Folding Knives

The Extrema Ratio BFK ZERO carries the character and mechanical precision of the full-size BFK in a smaller pocket-friendly format. Approximately 6.57 inches overall with a 2.68-inch N690 steel blade, ZERO is designed for discreet everyday carry without sacrificing confident handling.

The ambidextrous Crossbar Lock offers quick, fluid operation while keeping fingers outside the blade’s closing path. A reversible pocket clip supports convenient right- or left-handed carry. BFK ZERO configurations include machined aluminum, carbon fiber, G10 and Micarta handle options in the five distinct colors and materials of the BFK Series. It is an approachable entry into Extrema Ratio and a capable choice for experienced users who prefer a more compact folder. Explore every available BFK ZERO at Atlantic Knife.
