CobraTec CTK-1 Large OTF Knife 3.75" D2 Steel Drop Point Blade

The CobraTec CTK-1 Large delivers reliable out-the-front action with a 3.75-inch D2 steel blade engineered for demanding cutting tasks. This automatic knife combines precision manufacturing with tactical functionality, featuring a stonewashed aluminum handle that resists corrosion while maintaining a secure grip.

What Makes This Different

The CTK-1 stands apart from standard folding knives with its dual-action out-the-front mechanism that deploys and retracts the blade with thumb slider operation. D2 tool steel construction provides superior edge retention compared to standard stainless steel blades, maintaining sharpness through extended use. The stonewashed aluminum handle finish masks wear while reducing glare, making this knife suitable for both utility and tactical applications.
