Compact Reliability in Aviation Blue
The Extrema Ratio BFK Zero N690 Avio 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 77 g, it is a convenient choice for daily cutting tasks when a full-size folder feels too bulky. The understated blue G-10 handle gives the knife a clean, 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 handle’s aviation-inspired blue colour.
Machined G-10 handle scales resist moisture and temperature changes while providing 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.
