Ketuo Knife - Raijin

The Ketuo Raijin marks the debut design in our collaboration with Panurin, introducing a design language built around precision machining, layered geometry, and refined mechanical detailing. Modern and mechanical without becoming overly aggressive, the Raijin balances substantial construction with intricate details that reward a closer look. At its center is a 3.74" M390 blade, offered across a range of finishes including bead blast, DLC, stone wash, satin, and mirror polish. The broad blade profile provides a confident working edge while maintaining the clean geometry that defines the Raijin. The 6AL-4V titanium handle is where Panurin's design truly comes alive. Intricately milled handle inlays create layered visual depth and texture, complemented by an open-vented spine that exposes the mechanical structure of the knife. Sculpted thumb studs provide intuitive deployment, while precision pivot collars add another carefully considered detail around the knife's central hardware. Depending on configuration, the Raijin is equipped with titanium, zirconium, or Timascus inlays, with premium Timascus configurations also receiving matching Timascus pocket clips. A ceramic ball bearing pivot provides smooth, controlled action, while the titanium frame lock delivers solid and dependable blade retention. At 5.0 oz. (141.5g), the Raijin carries substantial presence without sacrificing its refined handling. From the intricate handle milling to the open spine and carefully integrated hardware, the Raijin demonstrates Panurin's ability to turn functional engineering into visual design. As the first design from our collaboration with Panurin, the Raijin establishes a distinctive foundation for what is to come. Purposeful machining. Distinctive architecture. Panurin design.
