The Extrema Ratio BF1 Classic is a cool, sleek pocket knife. Compared to the large pocket knives that Extrema Ratio normally produces, this knife can indeed bear the title Basic Folder (BF). Of course, that doesn't mean this knife has been made any less meticulously.
The blade is made from Böhler N690 steel. This is a very corrosion-resistant steel with good sharpness retention. The liner lock holds the blade in place. The anticorodal handles are lightweight, and thanks to the contours, this knife feels great in hand. The sleek deep-carry pocket clip completes the knife.
