Loading... Please wait...This is the unique and difficult to find MFK-1 skeletonized folder from Mission Knives made in a proprietary titanium alloy. Missionite is very superior wear resistance and can be “thru-hardened” to Rockwell C 47, while still maintaining its flexibility. At this strength and hardness, cutting edge retention is superior, plus, corrosion (including sea water) will not dull the knife cutting edge- a serious problem when using steel knifes. These knives are 40-50% lighter than their steel counterparts and nonmagnetic!
