CJRB Tundra ｜ The Ultimate Overbuilt Powerhouse

At CJRB, we believe a knife should be as resilient as the terrain it’s built to explore. The CJRB Tundra isn't just another folder; it’s a "pocket beast" designed for those who demand more from their gear.

Born from a need for uncompromising strength, the Tundra bridges the gap between a standard EDC and a heavy-duty tactical tool. Whether you’re batoning kindling at a backcountry campsite or tackling rigorous warehouse tasks, this series provides the confidence of a fixed blade with the convenience of a precision-engineered folder. With its massive profile and ergonomic grip, the Tundra is the workhorse that never backs down.
