When everything becomes chaos, you'll be glad you have this blade at hand. The MF-4 series of knives is the design that brought Mantis to where they are today in the industry. Its angular and very industrial appearance confuses the eye. The MF-4 knives are laser cut from a single piece of stainless, then 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 2, the steel is 154CM and the design is powerful.
