🔎 Comparison with other models
Compared to the Extrema Ratio BF2 R, the BF1 CD BLACK has a smaller blade (75 mm compared to 85 mm) and is lighter (88 g compared to 142 g), making it a more compact option for everyday carry. If you are looking for something larger, the BF2 R may be a better choice.
Compared to the Extrema Ratio RAO II, the BF1 CD BLACK is significantly smaller and lighter. The RAO II has a 110 mm blade and a more robust construction, but it is intended more for heavy-duty tasks than for everyday carry.
Compared to the Extrema Ratio MF1 BC, the BF1 CD BLACK has a shorter blade (75 mm compared to 95 mm) and is lighter, making it a better choice for discreet carry. The MF1 BC, in turn, is better suited to those who prefer larger folding knives with tactical use.
The BF1 CD BLACK is therefore the most compact and lightest of these models, making it an ideal choice for everyday carry and discreet use.
