Satre F N690 - Black Stonewash - Extrema Ratio

FOLDABLE – POCKET READY

Some designs go unnoticed. This one stands out immediately. The SATRE family identity goes pocket-sized. The SATRE F brings the signature toughness of Extrema Ratio into the compact folding knife segment. Lightweight to carry, impossible to ignore. Perfect in the pocket of high-end denim or an outdoor shirt: an icon of style and daily operational readiness.

LIGHTNING-FAST DEPLOYMENT. CHROMATIC IMPACT.

SATRE F is a compact folder designed for everyday carry (EDC). The flipper system ensures immediate and instinctive blade deployment. The structure utilizes a double steel liner, offering surprising rigidity in a featherweight build, supported by a rock-solid Liner-Lock mechanism. The handle scale features a milled window that reveals the blade color when closed, boosting aesthetic impact, especially in the versions featuring black blades and high-visibility colors. The "Deep Carry" wire clip ensures total concealment.

MAKE YOUR CHOICE

Six variants to define your style. The Böhler N690 steel models (Black and Stone Washed) offer the ultimate balance between edge retention and impact resistance, minimizing operational maintenance.

Completing the series is SATRE F OUTDOOR NITROGEN, dedicated to those seeking a tool born for the wilderness, the woods, and the field.
