CobraTec Large CTK-1 Carbon Fiber Automatic Knife

The Large CTK-1 Carbon Fiber model is among the most robust OTF knives from CobraTec, and in this version it combines full-size dimensions with a lightweight, modern carbon fiber handle. The result is a knife that feels premium while retaining a practical tactical character.

The knife’s dominant feature is a blade approximately 8.5–9 cm long, available in various profiles (including dagger and drop point depending on the variant). In this product line, the most common configuration is a versatile blade shape that offers a balanced ratio between cutting performance and tip strength.

As soon as you take the knife in hand, its larger size and secure grip are immediately noticeable. The Large CTK-1 belongs to the category of full-size OTF models that feel stable in hand and are suitable even for longer work without losing control.

The blade is made from D2 tool steel, which provides high hardness, good edge retention, and wear resistance. This material has long been proven in this category and is commonly used in EDC and tactical knives.

Operation is handled by a classic double-action OTF mechanism, allowing quick blade deployment and retraction with a single thumb movement. The mechanism is designed for reliable operation and immediate response.

The knife is equipped with a pocket clip for secure carry and a glass breaker, expanding its usefulness in emergency situations.

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