Detailed product description

Strength, reliability, and robust versatility in the field.

Extrema Ratio ONTOS II EXPEDITIONS 04.1000.0122/EXP is a fixed outdoor knife that combines Italian quality with practical features for expedition and survival use. Designed for demanding conditions, this model excels wherever a dependable, high-performance, and durable tool is needed.

Thanks to its full-size construction, quality steel, and thoughtful design, the ONTOS II Expeditions is an ideal choice for anyone who demands uncompromising performance – from fire prep and wood processing to demanding outdoor tasks and expedition situations.

The desert color combination and stonewashed blade finish emphasize its utilitarian character – it is ready to work where others are still figuring out how to begin.

Full Tang construction

Cordura sheath (M.O.L.L.E. compatible)

Character and philosophy

ONTOS II Expeditions is conceived as a universal survival knife that does not shy away from any task in nature. The full flat grind provides deep, clean cuts, while the ergonomic Forprene handle gives you a secure grip even in wet or extreme conditions.

The stable full tang construction together with a balanced center of gravity supports precise knife control and ensures that the ONTOS II Expeditions can handle heavier tasks as well – from wood processing to gear preparation during long expeditions.

Key benefits

  • Robust full tang construction – extreme strength and stability
  • Dark Stonewashed finish – blade protection and a discreet look
  • Ergonomic Forprene handle – secure grip even in wet conditions
  • Cordura sheath with M.O.L.L.E. – versatile carry and easy integration with gear
  • Survival accessories in the sheath – paracord with a flammable strand and a fire starter are practical in the field
  • Universal design – ideal for expedition and outdoor use

Possible limitations

  • Larger dimensions and weight are not ideal for minimalist EDC
  • N690 is a quality steel, but it requires regular maintenance for long-term sharpness
  • The flat grind may be less aggressive than some specialized profiles

Maintenance and care

  • Clean and dry the blade thoroughly after use
  • Keep the Cordura sheath free of sharp debris
  • Store the knife in a dry environment away from moisture

To maintain maximum blade sharpness, we recommend: Spyderco Tri‑Angle Sharpmaker Complete Sharpening System 204MF – a sharpening system that offers:

  • precise and consistent sharpening angles
  • gentle maintenance without removing excessive steel
  • safe use even without prior experience
