The MF-4 series of knives is probably the design that is responsible for bringing Mantis to where we are today in the industry. Its angular and very industrial appearance confuses the eye. Our MF-4’s are laser cut from a single piece of stainless, and finally 8 individual blocks of G-10 are screwed into the tang with 440-A stainless screws. This knife is without a doubt, a true tactical tool. This is the Chaos I, the steel is a standard 420HC, but the look is anything but standard.
