The CobraTec CTK-1 Large delivers reliable out-the-front deployment with a 3.75-inch tanto blade engineered for tactical applications. This dual-action OTF knife combines D2 tool steel construction with military-inspired aesthetics and practical features that set it apart from basic folding knives.
What Makes This Different
The CTK-1's dual-action mechanism fires the blade forward and retracts it with equal force, eliminating the weak spring systems found in cheaper OTF designs. D2 tool steel provides superior edge retention compared to standard stainless options, holding sharpness through extended cutting tasks. The partially serrated tanto profile maximizes cutting efficiency while the glass breaker tip handles emergency situations that would damage conventional knife points.
Key Features
- 3.75-inch D2 tool steel tanto blade with partial serrations for versatile cutting
- Dual-action OTF mechanism with ambidextrous thumb slide operation
- Army digital camouflage aluminum handle with textured grip surfaces
- Integrated glass breaker tip for emergency window breaking
- Deep carry pocket clip positioned for tip-up carry
- Safety lock prevents accidental deployment during transport
- Tanto point geometry optimized for piercing and utility tasks
Field performance centers on the blade's D2 steel composition, which maintains working sharpness through rope cutting, cardboard breakdown, and general utility tasks without frequent resharpening. The dual-action spring system provides consistent deployment force in temperatures from 20°F to 120°F, making it suitable for outdoor work, emergency response, and everyday carry applications. The aluminum handle resists corrosion while providing secure grip even when wet.
