Tactical medium folder with rear glass breaker, sub-hilt, reversible clip and semi-assisted opening. Length blade: 11 cm

The **Extrema Ratio MF2** is a large pocket knife, completely designed for tactical purposes. MF stands for Medium Folder. We do, however, feel it is a little large for a medium-sized pocket knife. With a total length of 26.8 cm this is even one of the largest pocket knives in our range.

This pocket knife was designed as such that it even feels great in hand while wearing gloves or if you have large hands. An additional 'pin' protrudes from the back of the handle. This is the sub-hilt. As such you have enough grip over the handle. The blade itself is made from Böhler N690 steel. This is a highly corrosion-resistant type of steel that is excellent for retaining sharpness. The liner lock ensures that the blade stays in place and the additional safety latch ensures it won't accidentally unlock. You open the MF2 with the flipper or thumb studs. So quickly! The back of the handle is enhanced with a glass breaker. With it you can safe the day during an emergency situation. 

Extrema Ratio produces knives for professionals. The MF2 is a perfect example.

General information

We always measure the blade height at the highest part of the blade.

Blade height

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.

Blade length

value_blade_length_edge

The length of the cutting edge is measured from the tip to the start of the edge. This may deviate from the manufacturer's specification.

Cutting edge length

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.

Blade thickness

value_closed_length

We always weigh a product as bare as possible. Knives and axes always without their sheath, lights (if possible) without their battery. For knife sets we measure the entire weight. This may deviate from the manufacturer's specifications.

Weight

Dimensions & weight

value_steel_hardness

The hardness in Rockwell C for a knife is always according to the manufacturer's specifications. When a manufacturer specifies a value of 56-58HRC, for instance, we always note the highest value, i.e. 58HRC.

Lock

We measure the sharpening angle ourselves. This value is the angle per side.  So 20º means that the total angle of the edge is 40º. Please note that knives are almost always sharpened by hand, even in factories. This value is therefore only an indication of a single tool measured by us. You are always free to choose your own sharpening angle. [Learn more about sharpening angles](/en/ct/sharpening-angles-explained.htm).

Sharpening angle

In terms of grind we are talking about how the complete blade thickness extends into the edge. Want to learn more about grinds? [Read all about grinds on knives](/en/ct/knife-grinds.htm).
