CobraTec Large CTK-1 Grey Cerakote Automatic Knife

The Large CTK-1 Grey Cerakote is one of CobraTec’s most popular OTF knives, and in this version it offers full-size dimensions for everyday carry as well as more demanding tasks. The grey Cerakote finish gives the knife a modern, tactical look while also increasing surface resistance to wear.

The knife’s standout feature is its drop point blade, approximately 8.5–9 cm long, offering excellent versatility. This profile is ideal for general cutting, field work, and everyday use because it combines good cutting control with a sufficiently strong tip.

As soon as you pick it up, its robust construction and secure grip immediately stand out. The Large CTK-1 feels solid and stable, while its larger dimensions provide noticeably better ergonomics than smaller OTF models.

The blade is made from D2 tool steel, which offers good hardness, long edge retention, and high wear resistance. It is a proven material in the category of working and EDC knives.

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

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

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