ABOUT THE MF0 FOLDER: Extrema Ratio has used the full-sized MF2 as the basic design for a compact version of the popular MF2 folder. Extrema Ratio has named this smaller version, the “MF0”[MF ZERO] folder. Shorter but definitely not shorted on quality or features. The MF0 is ideal for an EDC. A strong, solid, compact folder that rides easily in your pocket. The compact sized MF0 is a good option if you need a shorter blade due to local laws or if you prefer a shorter, easier-to-carry blade.

This version has the classic Testudo (black) finish and is offered with a drop point. This is a very durable finish that is very protective against corrosion and oxidation.

BLADE: The MF0 blade has been shortened compared to the other MF blades. The blade is less than 3 inches which makes the MF0 D a great EDC since some local laws limit blade lengths to 3 or 4 inches . This compact, clean blade shape is similar to the “leaf” shaped blade on the fixed blade Shrapnel OG. The blade is formed to include a lower guard with a lanyard hole. It has ambidextrous thumb stubs.

HANDLE: The handle on the MF0 has been reduced as much as possible to a minimum length. Even though the handle is somewhat shorter than the other MFs, it has been designed to give you a good grip. A window breaker on the end extends beyond the bridge clip. There is a supplementary screw you can adjust for fine-tuning the knife action.

LOCK: This folder has a liner lock. The MF0 offers you a solid, worry free, locking system that is standard on all the MF knives. The MF0 also have a manual lock which can be used to provide you with an additional level of safety.

CLIP: The MF0 has a reversible side-to-side clip. This clip is a "bridge" clip that wraps around the end so the knife sits deeper in your pocket for a more discreet carry. Only the bridge clip shows. It gives you a tip up carry.
