Extrema Ratio BFK Zero Stonewashed N690 Green Carbon Fiber folding knife
Compact Reliability, Carbon Fiber Character
The Extrema Ratio BFK Zero N690 Green Stone Washed brings the practicality and solid locking mechanism of the BFK series to a smaller, pocket-friendly format. Measuring 167 mm overall and weighing just 76 g, it is a convenient choice for daily cutting tasks when a full-size folder feels too bulky. The green carbon fiber handle gives the knife a distinctive, contemporary appearance.
The 68 mm flat-ground blade is crafted from Böhler N690 stainless steel, hardened to 58 HRC for a dependable balance of hardness and toughness. Its stonewashed finish complements the carbon fiber handle.
Machined carbon fiber handle scales combine rigidity with low weight, while the visible weave gives the knife its distinctive character. The contoured surface provides a secure grip with dry or wet hands. The same Crossbar Lock used in the full-size BFK holds the blade securely open and can be operated with one hand from either side, allowing the fingers to remain clear of the cutting edge’s path when closing.
A reversible pocket clip for left- or right-side carry and compact proportions make the BFK Zero a discreet companion for everyday use.
