The CobraTec Medium FS-3 OTF Automatic Knife in OD Green with a Tanto blade (brand part no. MODFS-3TNS) is a full-size out-the-front automatic built around a 3-inch D2 steel blade and an 8-inch overall length. CobraTec runs the FS-3 as a double-action automatic, so the top-mounted button both fires the blade out and retracts it, and the OD Green handle gives the knife a distinct look apart from CobraTec’s standard black finishes. The tanto point adds extra tip strength for piercing tasks compared to a standard drop point. Among our automatic knives, the Medium FS-3 suits everyday carriers who want a full-size double-action OTF with genuine D2 steel performance.
