MF stands for Medium Folder. This line of knives falls between the Basic Folders and Heavy Folders series. The typical mechanism of the series is the LINER-LOCK. The overall structure is sturdy, and all knives in the MF series have a rear glass breaker. They also feature the innovative counter-adjustment screw for the blade fixing bracket. By removing the counter-screw, it is possible to adjust the central pivot to achieve the desired opening fluidity. Once adjusted, the pivot can be locked in place with the counter-screw. Hemispheric milling on the handle facilitates grip changes from a "saber grip" to a "reverse grip". The clip is also reversible. The MF0 is the smallest knife in the MF series and is essentially a compact version of the MF1. It retains all the features of the MF1, with the exception of a shorter handle and blade, which is very similar to the blade of the SHRAPNEL OG backup knife.
