The Extrema Ratio BF2 CD is a sizable pocket knife crafted specifically for first responders needing a sturdy, reliable tool. Slightly larger than the Extrema Ratio BF1, the BF2 is a "full-size" folding knife, ideal for military and law enforcement personnel in the field. The handle is durable and comfortable to hold, with a reversible clip that provides a secure thumb rest for a "reverse" grip. Unique recessed areas in the handle allow easy access to the opening pins, which remain flush with the knife when it’s closed.

 

The blade is flat-ground with a drop-point shape, equipped with the trusted liner-lock mechanism, and includes an additional, manually-activated secondary lock with a protective cover. This BF2 model features M390 stainless steel with a black Diamond-Like Carbon (DLC) coating for added durability and a sleek appearance.
