Extrema Ratio 04.1000.0463/EXP Sethlans Expeditions
The Extrema Ratio 04.1000.0463/EXP Sethlans Expeditions is a premium fixed-blade survival knife developed for professional users, outdoor enthusiasts, and expedition environments where reliability is essential. Part of Extrema Ratio’s Expedition Series, this knife is designed in collaboration with Master Advanced Instructor Daniele Dal Canto, combining proven materials with practical field-ready features.
The blade is crafted from premium BÖHLER N690 steel, hardened to 58 HRC and treated with MIL-C-13924 burnishing for enhanced corrosion resistance and durability. Its Dark Stone finish provides a low-reflective appearance while maintaining a rugged aesthetic suitable for demanding outdoor conditions.
Featuring ergonomic desert-colored G10 handle scales mounted to a skeletonized full-tang construction, the Sethlans Expeditions offers excellent grip, strength, and reduced weight. The handle can also be wrapped with paracord for additional customization and functionality.
The knife includes a lightweight modular Kydex sheath that supports both left- and right-hand carry, with vertical or horizontal mounting options when paired with the optional belt clip. A MOLLE-compatible mini pouch is also included, containing paracord with a flammable filament and a Firesteel to support emergency fire-starting in the field.
