It's the perfect balance between presence and size. BFK MICRO inherits the indestructible spirit of Extrema Ratio, a manufacturer of high-performance blades for nearly three decades, and translates it into a perfect size for everyday carry. Scales are milled for total grip, tolerances are zero, and the blade is designed to work hard. If the Pixel is the full-size, the Micro is the answer for those seeking maximum efficiency in the space of a palm.

How will you carry it?
The standard sheath is a complete black Kydex system with a double Malice clip for belt carry, but its proportions make it even more natural to carry around the neck or in a backpack. It also includes paracord for attachment to MOLLE systems or to any item with a loop or ring: from a jacket pocket to an everyday bag. Optional accessories are available for more specific needs: Clip, UltiClip, Belt Clip, and shoulder strap. The MICRO is always with you. Every day.

Two steels. Choose yours.
Five variations, two fonts. Pick your favorite:

MAGNACUT (Black and Tactical Mud handle): Burnished blade, aluminum scales, black ring and hardware. Best-in-class edge retention, combined with a corrosion resistance that, before this steel, seemed incompatible with such performance. If you demand the best that metallurgy can offer from your edge, your search ends here.

NITROGEN (Green Carbon Fiber, Tobacco Micarta, and Avio G10 handle): Satin-finished blade, steel ring, and hardware. Nitrogen is the Extrema Ratio technical specification: steel selection, processing, and a dedicated heat treatment cycle. The practical result? An edge that sharpens in a few simple steps wherever you are, and superior rust resistance that requires minimal maintenance. Not to mention the most textured scales in the range: the texture of Green Carbon Fiber, the warmth of Tobacco Micarta, the coolness of Avio G10. If you truly use a knife every day, this is for you.
