FOLDABLE – POCKET READY 

There are designs that go unnoticed. This is immediately noticed. The identity of the SATRE family becomes pocket-sized. SATRE F brings the typical robustness of Extrema Ratio to the compact foldable segment. Light to carry, impossible to ignore. Perfect in the pocket of a fashionable jeans or in that of an outdoor shirt: an icon of style and daily operation. 

OPENING LIGHTNING. CHROMATIC IMPACT. 

SATRE F is a compact lockable designed for the daily EDC. The flip system ensures an immediate and instinctive blade opening. The structure uses a double steel folder, offering surprising rigidity in a featherweight, supported by a solid Liner-Lock mechanism. The cheek has a milled window that gives a glimpse of the color of the blade when the knife is closed, increasing the aesthetic impact, especially in the versions with black blade and bright colors. The “Deep Carry” thread clip ensures total concealability of the knife. 

MAKE YOUR CHOICE 

Six variations to define your style. The Böhler N690 (Black and Stone Washed) steel models offer the best balance between wire tightness and impact resistance, while minimizing operational maintenance. 

The Nitrogen steel versions (Periwinkle, Orange and Yellow) ensure a very high corrosion resistance and minimal maintenance, with a strong aesthetic that does not go unnoticed. 

The series is completed by the SATRE F OUTDOOR NITROGEN model, dedicated to those looking for a tool created to be outdoors, in the woods and in the field. 

Every color choice responds to a precise identity.
