Extrema Ratio BF0 R CD Desert HCS Knife – 04.1000.0461
Meet the BF0 R CD Desert, the latest evolution in Extrema Ratio’s iconic Basic Folder series. Expertly engineered for adventurers, urban explorers and anyone who demands supreme performance in a pocket-ready package, this knife fuses cutting-edge materials with rugged Italian design. At just 140 mm overall and weighing a mere 53 g, it tucks into your pocket without slowing you down—but when duty calls, it delivers full-size power and precision.
The handle is molded from reinforced technopolymer over a steel internal frame, offering feather-light strength and an ergonomic grip that resists abrasion, chemicals and extreme temperatures. Deploying the razor-sharp Böhler N690 stainless steel blade is as swift as it is satisfying thanks to the High Speed Razor Opening System: a single flick and you’re ready to slice, whittle or pry with confidence. Once open, the proven LINER-LOCK mechanism locks the blade securely in place, so you can tackle tough tasks without hesitation.
Every detail of the BF0 R CD Desert is crafted for real-world performance. The stone-washed finish conceals daily wear, while the compact, flat-ground blade geometry delivers exceptional bite and effortless sharpening in the field. Whether you’re camping in the wilderness, rigging gear around the workshop or simply opening packages at home, this pocket powerhouse excels.
Choose between two striking versions: “Desert” with its sand-tone HCS handle and matching stone-washed blade, or “Stone Washed” with a stealthy black grip. Both share identical specs, so pick the style that matches your gear and personality.
Elevate your everyday carry with the Extrema Ratio BF0 R CD Desert: where minimal footprint meets maximum reliability. Experience the joy of a perfectly balanced, precision-crafted folder that’s always at the ready.
