CobraTec Large CTK-1 Grey Cerakote OTF Knife

The Large CTK-1 Grey Cerakote (LGYCTK-1LDAGNS) is one of CobraTec’s most popular OTF knives, offering a full working size combined with a durable grey Cerakote finish. This provides increased protection against wear and corrosion while giving the knife a clean, tactical look.

The dominant feature of the knife is an approximately 8.5–9 cm drop point blade. This profile is highly versatile – well suited for everyday cutting tasks, field work, and regular EDC use, as it combines precision with a strong, stable tip.

As soon as you pick it up, the knife feels robust and confident in hand. The Large CTK-1 is a larger OTF model that offers better ergonomics and grip stability than compact variants, which you will appreciate during longer work sessions and quick handling.

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 EDC and tactical knives, where blade longevity is important.

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

The construction includes a pocket clip for secure carry and a glass breaker, which expands the knife’s usefulness in emergency situations.

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