The CobraTec CTK-1 Large delivers reliable out-the-front deployment with a 3.75-inch D2 steel blade engineered for demanding cutting tasks. This tactical knife combines precision engineering with practical features that set it apart from standard folding knives.

What Makes This Different

The CTK-1's double-action OTF mechanism fires the blade forward and retracts it with the same sliding switch, eliminating the need for manual blade closure. D2 tool steel provides superior edge retention compared to standard stainless options, maintaining sharpness through extended use. The integrated glass breaker transforms this knife into a multi-purpose emergency tool, while the part-serrated edge handles both precision cuts and aggressive material processing.

Key Features

• 3.75-inch D2 tool steel blade with exceptional edge retention and wear resistance
• Double-action out-the-front mechanism for one-handed operation
• Drop point blade geometry with partial serrations for versatile cutting applications
• Black aluminum handle construction balances durability with lightweight carry
• Integrated glass breaker for emergency situations
• Removable pocket clip for secure everyday carry
• Ambidextrous firing switch accommodates left and right-handed users

The CTK-1 performs consistently in tactical, utility, and emergency scenarios where rapid blade deployment matters. D2 steel's high carbon content delivers cutting performance that outlasts conventional stainless blades, while the OTF action functions reliably in conditions where folding knives might bind or fail. The glass breaker feature adds critical capability for vehicle extraction or emergency response situations.
