Wet wood, dirty hands, hours of work.
Carve, cut, prepare, finish.
When the context decides the rules, Extrema Ratio knives from the OUTDOOR series are ready to stay out as long as you.
The Extrema Ratio Outdoor line was born from a simple principle: when you're out, the superfluous weighs.

It's a series designed for outdoor use in the field, with dedicated finishes and solutions: green handles for environmental integration, stonewashed or satin-finished blades for easy maintenance, high-visibility paracord, and essential, durable sheaths. Fewer unnecessary accessories. Same reliability, same quality, same performance.

The knives of the Outdoor series interpret this philosophy in a compact form: light, reliable, ready for hard work.

The FOK Outdoor is a fixed blade knife for real outdoor use, designed for field use, where weight, size, and reliability make the difference. It's based on the FOLGORE model and reinterpreted for the outdoors, with materials and finishes optimized for the woods, fields, and extended outdoor activities.

Compact and lightweight, it is designed to accompany you on long days of bushcraft, camping and outdoor work, in your backpack or on your equipment, without becoming an unnecessary burden.

The blade maintains a slim yet structurally solid profile, ideal for bushcraft, advanced camping, preparation, and everyday outdoor work. The tip promotes precision and control in practical tasks, where an outdoor knife must respond immediately and predictably.

The green-scaled handle is designed to offer ergonomics and a secure grip, even with dirty, wet, or tired hands. A functional choice that reduces visual impact and blends in with the natural surroundings.
The high-visibility orange paracord is a safety choice: when the knife falls, when the terrain is confusing, finding it becomes essential.

Completing the system is a lightweight, durable, thermoformed Kydex sheath that doesn't absorb water and requires no unnecessary maintenance.
