We gather up a bevvy of top stateside-manufactured automatic knives, certain to give you an edge on fast deployment. The version of the crossbar lock Bear Ops calls the Slide Lock serves as both the blade lock and firing mechanism of the KATAKT II. From the closed position, the KATAKT II uses the Slide Lock as both the blade lock and release. Function and durability are built into the skull pocket clip of the Pro-Tech/Chaves Knives 229. The auto carries tip up via a distinctive Chaves pocket clip design in the shape of a skull.
