The Benchmade Infidel double action out the front automatic knife, designed by McHenry & Williams, is a favorite amongst law enforcement and military professionals around the globe and is praised for its rugged construction and solid durability . The design of the black anodized 6061-T6 aircraft grade aluminum handle boasts a milled design that transitions into the design of the slide trigger. On the black dagger style blade, you will find a blood groove that runs the length of the almost 4″ blade on both sides that further enhances the already aggressive nature of this black class model. Furthermore, the enlarged slide trigger is housed on the broad side of the handle scale allowing for better accessibility, even while wearing gloves. This model features a black aluminum chassis, a dual-edged dagger style blade in a black finish and the deep carry pocket clip is statically designed for tip down carry only. Due to the size, this knife comes with a MOLLE compatible nylon sheath and malice clip for multiple carry options. Made in the USA.
