BFK ZERO N690 TACTICAL MUD

The Extrema Ratio BFK ZERO N690 TACTICAL MUD is the compact version of the BFK series, designed for discreet everyday carry and versatile daily work. Despite its compact dimensions, the ZERO features the same Crossbar Lock mechanism as the full-size BFK.

Precisely milled handle scales, tight manufacturing tolerances and a carefully engineered construction provide a secure grip and solid handling. The blade is made from Böhler N690 steel, hardened to 58 HRC, and features a MIL-C-13924 burnished finish.

Crossbar Lock

The Crossbar Lock secures the blade with a play-free lockup and allows comfortable one-handed operation. The mechanism can be operated from either side. During closing, the fingers remain clear of the blade's edge path, allowing the blade to be closed in a controlled manner.

Compact Everyday Carry

With an overall length of 16.7 cm, the BFK ZERO is particularly compact. The reversible pocket clip allows fully ambidextrous carry and keeps the knife discreetly positioned along the edge of the pocket.

At just 85.5 g, the ZERO is an ideal choice when a full-featured folding knife should take up as little space as possible.

TACTICAL MUD – A Warmer Tone

The TACTICAL MUD version combines an Anticorodal anodized aluminum handle with a burnished blade. The precisely milled aluminum handle scales provide a secure grip while giving the knife a technical and robust appearance.

Compared with the black version, Tactical Mud features a warmer color while retaining the same construction and technical specifications.
