Designed by the Legendary Colonel Rex Applegate, a man who knew as much as anybody about close quarters combat, these knives embody his vision of a folding combat knife. Gerber's Applegate-Fairbairn line of knives are one-handed opening, liner lock knives ideal for many situations. The Covert is a 3/4 version of the Combat Folder. Designed for inconspicuous carry, the Covert has a reversible stainless steel pocket clip. With an opening stud on both sides, this knife is easily adapted to for left-handed use. The black titanium coated blade is made from ATS-34 stainless steel and coated with black titanium nitride. The Covert also is the first product to incorporate the Interlock, a Gerber exclusive. This is a safety that firmly locks the liner in place, preventing accidental unlocking of the blade.
