TKOR-4.5 SERE Ranger Green
Description
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.

Awesome design, great balance, premium materials. The fit and finish is amoung the best I have experienced.
Just place my 8th order for my first Toor folding knife.
This knife is completely bad ass!! I’ve already tested it out in the field, and it can withstand almost anything. It definitely leads the way!! I would recommend this knife to anyone who definitely is looking for a knife as a weapon or as a tool.
Unbelievable knife and absolutely ready to go into battle. Blade shape, tip completely centered on center line, blade thickness, full tang, grip on the handle very secure, index finger locked in, lanyard hole, all perfect. This is my first TOOR knife and I am extremely satisfied with it. I will be buying others. I wish TOOR our knives would offer a slightly shorter version as well as holster for both that was very secure (no accidental loss) and could be carried Scout style. Thank you TOOR
Awesome products. Well designed and expertly manufactured in the U.S.A.
Fantastic customer service. Personal, professional and friendly.
Will definitely purchase more items from Toor!
