The **Extrema Ratio BFO** is the smallest pocket knife in the Extrema Ratio range. The blade is just 5.5 cm long. This makes the BFO particularly suitable for everyday use or as a backup pocket knife alongside a larger knife.

You open the blade of this version with the thumb hole, then a solid liner lock locks the blade in place. You can carry the BFO with the pocket clip, or simply put it in your pocket without using the clip.

## Böhler N690 steel blade

The blade is made from Austrian Böhler N690 steel. This is a stainless steel with long sharpness retention that is also used for surgical tools. N690 is highly durable and can be sharpened until razor sharp.

## Nylon handle

The handle is made from nylon, a strong yet lightweight material. It also has the advantage that it doesn't get very hot or cold like steel or aluminium, so it is practical in extreme weather conditions.

## Extrema Ratio: Italian knives for professional use

The Italian brand Extrema Ratio has been producing sleek tactical knives for professional use ever since 1997. This includes first responders such as soldiers, police officers and firefighters. Extrema Ratio knives are made to adhere to the highest military standards. These knives are produced in cooperation with the Italian army which carefully tests and carries them. The result: proven, top-quality products. Unparalleled in the world of tactical knives.

We always measure the blade length ourselves. This is the length of the blade from the tip to the front of the handle. This may deviate from the manufacturer's specification.

We always measure the blade thickness at the thickest part of the blade. Often just before the handle. This may deviate from the manufacturer's specification.
