EX133MF2: MF2 Series Folder
Extrema Ratio
The Medium Folder MF series from Extrema Ratio are mid-sized offerings with all the strength of a fixed blade. They range in size from the MFO which is the smallest at 7.13" overall, to the MF3 which is a whopping 10.43" overall, depending on your particular needs. However, they all share the same basic design and features. All MF knives are built for tactical applications and come equipped with a rear glass breaker. They have a circular milled spot on the handle which makes it easier to change the grip position from saber to reverse grip. They have a reversible, deep carry pocket clip and the double screw pivot enables the opening regulation strength. The handle designs change slightly with the variations in size but all are very ergonomic and have multiple jimped areas for a sure grip. You will be ready for anything when you're carrying an MF folder from Extrema Ratio, they are built as strong as any folder on the market. The MF2 features a sub hilt which makes the grip extremely stable and avoids slippage of the hand on the blade, while guard enables a fast opening when pushing it with the index finger.

not worth the money
i got this knife in the spring. the price tag was quite high and i don't really think it is worth what i paid. the knife wasn't terrible. the only major issues i had with it were that the lock was built poorly and would gouge my thumb to the point of almost bleeding when i would close it and I removed the pocket clip and when i went to reinstall it, all the threaded holes stripped. thank god i got my money back. i would go with another Zero tolerance.
