The CobraTec CTK-1 Large OTF knife is a serious tool for hunters, tactical users, and anyone who needs reliable, fast blade deployment in the field or on duty. This 3.75" out-of-the-front drop point blade cuts hard and holds an edge, and the partial serrated D2 steel edge gives you versatility—smooth cuts for clean work and aggressive teeth for rough jobs like rope or synthetic materials. Whether you're processing game, working camp, or carrying for personal defense, the CTK-1 delivers the speed and performance OTF users demand.
Built on a carbon fiber aluminum handle, the CTK-1 feels balanced and durable without unnecessary weight. The glass breaker at the pommel adds utility beyond the blade—a genuine safety feature if you ever need it. The integrated pocket clip keeps the knife accessible and ready, so you can carry it consistently without fumbling. CobraTec's engineering means smooth, reliable firing and a robust lock-up, the kind of quality you trust when a tool needs to perform.
This is a no-nonsense OTF for work and backcountry use: a knife that deploys instantly, holds its edge through the day, and won't let you down when the conditions get real. If you run heavy gear and need a blade that keeps up, the CTK-1 belongs in your kit.
