The CobraTec CTK-1 Large is a purpose-built OTF (out-the-front) knife designed for users who need reliable, fast blade deployment in tactical, professional, or emergency situations. This large OTF knife features a 3.75" drop point blade made from D2 steel—a proven tool steel that holds an edge well and resists corrosion better than many carbon alternatives. The NYPD blue aluminum handle pairs durability with a professional aesthetic, while the integrated glass breaker gives you a secondary tool for emergency egress or vehicle rescue scenarios. A pocket clip keeps it accessible and ready.
D2 steel is a midrange tool steel that many professionals trust for its balance of edge retention and ease of sharpening. The drop point blade geometry makes this knife versatile: it's strong at the tip for detailed work, yet the belly of the blade is ideal for slicing. Whether you're a first responder, law enforcement trainer, tactical operator, or serious EDC carrier, the CTK-1 Large delivers the speed of OTF deployment without compromise on steel quality or handle construction.
CobraTec builds knives for people who use them hard. The aluminum handle won't rust, and the OTF mechanism is engineered for reliability. This is a knife that earns its place in a duty belt, go-bag, or everyday carry rotation—no fuss, no marketing fluff, just a solid large OTF blade ready when you need it.
