SETHLANS S600 OUTDOOR

Hardwood, fire, camp, repetition.
Cutting, carving, preparing, adapting.

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

Based on the original Sethlans – already well regarded as a bushcraft and survival knife – it is reinterpreted in the Outdoor configuration with functional solutions specifically developed for field operations.
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 outdoor fixed blade is engineered to perform for extended periods without requiring complex maintenance.

Blade & Performance
The full tang construction ensures maximum rigidity and mechanical continuity: no interruptions, no hidden weak points.
The blade retains the proven Sethlans geometry, optimized to deliver control, cutting efficiency, and structural strength in bushcraft and survival tasks.

The Outdoor Stone Washed finish is selected for demanding use: less sensitive to wear marks, easier to maintain, and more tolerant of dirt and moisture – fully consistent with a professional-grade outdoor knife.

Handle & Configuration
The handle features green G10 scales with the Extrema Ratio ergonomic design, providing a secure grip even with wet, dirty, or fatigued hands.

As with other Sethlans models, the scales are removable: the skeletonized tang allows weight reduction and alternative configurations, including paracord wrapping for users seeking functional handle customization.

The high-visibility orange paracord lanyard included in the Outdoor configuration adds an important safety feature: rapid tool recovery when terrain or vegetation conceals the knife.

Outdoor Sheath
Sethlans Outdoor is supplied with a lightweight, minimalist Kydex sheath designed for continuous outdoor use:
does not absorb water, does not retain moisture, requires minimal maintenance, configurable for right- or left-handed users.

Compatible with optional mounting systems, it supports multiple carry solutions on belts, gear, and modular platforms.

Carry Configurations

The sheath system is modular and adaptable to equipment and outdoor scenarios:
MOLLE-ready – direct attachment via paracord to backpacks and modular systems
Clip – quick, discreet belt or pocket carry
Ulticlip – secure attachment even without a belt
Malice Clip – horizontal mounting on belts and duty belts
Belt Clip – horizontal and/or vertical belt carry
Shoulder strap – concealed and balanced carry during dynamic activities

A compact platform designed to adapt to duration, environment, and operational style.

SETHLANS OUTDOOR

Control. Durability. Reliability.

This is why Extrema Ratio defines it as professional outdoor equipment: because the level of reliability required is the same as in operational use.
