Small enough to forget you're carrying it. The BFK NANO takes the practicality of fixed-blade EDCs to its most compact level. Stripped down to the essentials to fit in the tightest spaces, from a pocket organizer to an everyday bag, it maintains the same meticulous craftsmanship and uncompromising approach as its two bigger siblings, the BFK MICRO and BFK PIXEL. High-grip milled scales, zero tolerances, and zero bulk: the ideal solution for those seeking pure functionality without bulking up their pockets.

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 NANO 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.
