The CobraTec CTK-1 Large 3.25-inch Black Tanto OTF Knife brings CobraTec’s CTK-1 lineup to black finish, built for shooters and everyday carriers who want a fast, reliable blade on hand (CobraTec part no. LBCTK1LTNS). It pairs a 3.25-inch tanto blade in D2 tool steel with CNC-machined 6061 aluminum alloy construction, sized for large-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. Between range days, work, and everyday tasks, it’s built to come out of the pocket ready.
