CobraTec Large CTK-1 Orange Cerakote OTF Knife

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

The knife’s defining feature is its tanto blade measuring approximately 8.5–9 cm (approx. 3.25–3.5″), which provides excellent tip strength and very good penetrating ability. This profile is ideal for tougher work as well as tactical use.

As soon as you pick up the knife, its solid and robust construction stands out immediately. The Large CTK-1 feels secure in hand, and thanks to its larger dimensions it offers noticeably 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 one-handed blade deployment and retraction. The mechanism is designed for reliable function and instant response.

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

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