The CobraTec Large FS-3 dual-action OTF knife (brand part no. LBFS-3DNS) is a fully automatic out-the-front folder built by CobraTec Knives around a 3.5-inch drop-point blade in D2 tool steel with a satin finish. A single side-mounted button both fires and retracts the blade, giving fast, reliable deployment with one hand. The black 6061-T6 aluminum handle is ambidextrous, with a switchable pocket clip and a built-in glass breaker at the pommel for emergency use. Backed by CobraTec’s lifetime warranty and shipped with a nylon sheath, this knife is built for the EDC carrier who wants a larger-format automatic with a versatile drop-point edge.
