The Extrema Ratio BF0 [BF zero] is the smallest of the basic folder series. Its blade length [under 3 inches] makes the BF0 an excellent choice for areas where knife blade length is severely restricted. Also, it is a good knife for young knife owners - functional but not intimidating. A great knife to drop into your pocket for a discreet carry. A great knife for ladies to drop into a handbag.

Extrema Ratio is using a different material for the BF0 handle. Instead of the anticorodal aluminum used in the other basic folders, Extrema Ratio is using technopolymer. The handle has a slot for a lanyard. The BF0 internal frame is made of steel. The lock is a liner lock. The stone washed blade has a drop point, and a cutout section making it easy for you to open the folder.

Has the distinctive Italian design that identifies it as being an Extrema Ratio folder plus the quality that Extrema Ratio knives are known for. Lightweight but rugged.
