The Extrema Ratio BF1 Classic is a cool, super sleek pocket knife. Compared to the large pocket knives that Extrema Ratio normally produces, this knife could indeed bear the title Basic Folder (BF). Of course, that doesn’t mean this knife has been made any less meticulously.
£145.45 Original price was: £145.45.£95.99Current price is: £95.99.
