Extrema Ratio Sethlans S600 Outdoor

Product detailed description

When the environment sets the rules, the Extrema Ratio OUTDOOR series knives are designed to stay operational as long as you are.
The Extrema Ratio Outdoor series is built around a simple principle: when you’re out in the field, excess weight is a liability.

This series is specifically engineered for real outdoor use, featuring dedicated finishes and solutions: green handles for environmental integration, Stone Washed or Satin finished blades for easy maintenance, high‑visibility paracord, essential and rugged sheaths.

Fewer unnecessary accessories. The same reliability, the same quality, the same performance.
Outdoor series knives embody this philosophy in the most direct way: real tools, ready for work.

Sethlans S600 Outdoor is a fixed blade knife designed for bushcraft, survival, prepping, and prolonged outdoor use.

It is a tool conceived for repetitive work on wood, rope, and natural materials, for camp management, and for all activities where control and durability matter more than aesthetics.

Compact in thickness yet structurally robust, this is an outdoor fixed blade engineered to perform for extended periods without requiring complex maintenance.
