CobraTec Large CTK-1 Orange Cerakote OTF Knife

The CobraTec Large CTK-1 Orange Cerakote LORCTK-1LDAGNS automatic knife is a robust OTF model designed for everyday use, combining bold design, durable construction, and a reliable automatic mechanism in a full-size format.

The CTK-1 is one of CobraTec’s most popular OTF knives, and in the Large version it offers full-size dimensions for comfortable everyday carry as well as more demanding tasks. The striking orange Cerakote finish increases surface durability while also ensuring high visibility.

A dominant feature of the knife is its blade measuring approximately 8.5–9 cm (approx. 3.25–3.5″), providing sufficient performance for a wide range of EDC tasks as well as more demanding cutting jobs. The drop point profile offers an ideal combination of control, strength, and versatility.

As soon as you take the knife in hand, its solid and robust construction stands out immediately. The Large CTK-1 feels secure in the hand, and thanks to its larger dimensions, it provides significantly better ergonomics than compact OTF models.

The blade is made from D2 tool steel, which offers good hardness, long edge retention, and solid wear resistance. This material is a proven standard in the EDC knife category.

Operation is handled by a classic double-action OTF mechanism, allowing fast blade deployment and retraction with one hand. The mechanism is designed for reliable operation and immediate response.

The construction includes a pocket clip for safe and comfortable carry. A glass breaker is also present, expanding the knife’s usefulness in emergency situations.

The knife comes in typical CobraTec packaging and is covered by the manufacturer’s lifetime warranty.
