The CobraTec CTK-1 Medium delivers reliable out-the-front deployment with a 3-inch tanto blade engineered for tactical applications. This dual-action automatic knife combines D2 tool steel construction with aircraft-grade aluminum housing for professionals who demand consistent performance.
What Makes This Different
The CTK-1 features CobraTec's refined firing mechanism that provides smooth blade deployment and retraction with minimal maintenance requirements. Unlike spring-assisted folders, this OTF design eliminates blade play and maintains consistent lockup strength through thousands of cycles. The D2 steel blade holds a sharp edge significantly longer than standard stainless options while the NYPD blue anodized finish resists corrosion and wear.
Key Features
- 3-inch D2 tool steel tanto blade with plain edge for superior edge retention
- Dual-action out-the-front mechanism for one-handed operation
- NYPD blue anodized 6061-T6 aluminum handle construction
- Integrated glass breaker tip for emergency applications
- Deep carry pocket clip positioned for tip-up carry
- Tanto point geometry optimized for piercing and utility tasks
- Ambidextrous thumb slide activation
Field testing demonstrates the CTK-1's reliability across temperature ranges from -10°F to 120°F without deployment failures. The D2 steel composition (1.5% carbon, 12% chromium) maintains working sharpness through extended cutting tasks while the aluminum handle provides secure grip even when wet. Law enforcement and emergency responders appreciate the glass breaker feature and single-handed operation capability.
