TKOR-4.5 SERE Ranger Green

Toor Knives × Onward Research Collaboration

When everything goes sideways, your blade becomes more than a tool; it becomes your lifeline. The TKOR-4.5 SERE was created from that understanding. Developed jointly by Toor Knives and Onward Research, this fixed blade was designed around the uncompromising demands of SERE training (Survival, Evasion, Resistance, and Escape) for those who operate at the edge of control. This partnership makes sense at every level.

Toor Knives, born from the mindset of American warfighters, brings its San Diego-based precision manufacturing and lifetime-guaranteed hard-use craftsmanship. Every knife is made under the flag, by people who’ve carried blades for real.

Onward Research, founded on the principle that good gear should be simple, scalable, and purpose-driven, builds modular systems designed for those who live and train with intent. Their philosophy, refine, never overcomplicate, aligns perfectly with Toor’s mission-ready ethos.

Together, the brands created a knife that bridges the gap between field craft and combat readiness, a tool you can depend on when survival isn’t theoretical.
