The CobraTec CTK-1 Medium 3-inch OD Green Tanto OTF Knife brings CobraTec’s CTK-1 lineup to od green finish, built for shooters and everyday carriers who want a fast, reliable blade on hand (CobraTec part no. MODCTK1MTNS). It pairs a 3-inch tanto blade in D2 tool steel with CNC-machined 6061 aluminum alloy construction, sized for medium-frame carry. Deployment is dual-action out-the-front (OTF) — a single top switch fires the blade forward and pulls it straight back in, no manual folding needed. It suits everyday carry, hunting camp chores, or a fast-access utility role equally well.
