Designed by the legendary Colonel Rex Applegate, these knives are one hand opening. The combat folder has a double beveled blade and comes with a ballistic sheath. The Covert is a 3/4 version of the combat folder. The Covert has a reversible stainless steel pocket clip. With an opening stud on both sides, this knife is easily adapted for left handed use. The blade is made from ATS-34 stainless steel. It has an Interlock safety that firmly locks the liner in place, preventing accidental unlocking of the blade.
