Extrema Ratio RAO Folder Black Ruvido

The Extrema Ratio RAO Folder in Black Ruvido is a purpose-built tactical powerhouse, engineered for extreme reliability in the harshest conditions. Measuring 5.63" closed, it deploys a formidable 4.75" tanto blade crafted from premium Böhler N690 stainless steel, finished in a rugged MIL-C-13924 burnished black coating for superior corrosion resistance and durability. The black textured aluminum handle offers a solid, no-slip grip, while the integrated lanyard hole adds versatility in carry and retention. What truly sets the RAO apart is its reinforced safety system—a steel locking pin that can be manually screwed into place, effectively transforming the folder into a fixed blade for maximum strength and security. The included sheath is not just an accessory—it’s a critical part of the system. MOLLE-compatible and built for tactical deployment, it features a diamond-plate sharpener and allows for multiple carry options: secure the knife in the open position using cord and clips for rapid access, or carry it closed in the front pocket. Easily mounts to belts or tactical gear for mission-ready convenience.
