CobraTec Knives CTK-1 Large 3.75" OTF Tanto Plain D2 Steel Carbon Fiber Aluminum Handle

The CobraTec CTK-1 is a Large out-the-front automatic knife built around a 3.75" tanto blade in D2 tool steel with a plain edge. The dual-action trigger fires the blade forward and retracts it with a smooth, reliable motion for rapid one-handed deployment.

The handle combines a carbon fiber scale over a zinc-aluminum alloy chassis, giving the knife a confident grip while keeping weight in check at 9 oz. At 9.50" overall with a 5.75" closed length, the Large CTK-1 carries comfortably and rides in the pocket on the included pocket clip. A glass breaker is integrated into the butt end for emergency use, and a nylon sheath is included for belt or pack carry.

D2 is a high-carbon, high-chromium tool steel that holds an edge well and resists wear, making it well-suited to daily cutting tasks, while the tanto profile delivers a strong tip for piercing and detail work. Built for EDC, tactical, and general utility use, the CTK-1 is backed by CobraTec's lifetime warranty.
