CobraTec FS-3 Medium 3-inch Stonewashed Tanto OTF Knife

CobraTec’s FS-3 line adds the CobraTec FS-3 Medium 3-inch Stonewashed Tanto OTF Knife to the catalog, built for shooters and everyday carriers who want a fast, reliable blade on hand (CobraTec part no. MSWFS-3TNS). It pairs a 3-inch tanto blade in D2 tool steel with aluminum alloy construction, sized for medium-frame carry. Deployment is dual-action out-the-front (OTF) — the same control switch both deploys and retracts the blade. It’s a solid pick for EDC, home defense, or as a fast-access utility blade.
