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

The CobraTec CTK-1 Large delivers reliable out-the-front action with a 3.75-inch D2 steel dagger blade designed for tactical applications and everyday carry. This automatic knife combines precision engineering with practical features including an integrated glass breaker and secure pocket clip for professional users who demand consistent performance.

What Makes This Different

The CTK-1 stands apart from standard OTF knives through its robust D2 tool steel construction and stonewashed aluminum handle that resists wear and corrosion. While many tactical knives use softer steel alloys, D2 steel maintains its edge longer and provides superior cutting performance across demanding applications. The double-action mechanism fires and retracts smoothly with consistent spring tension rated for thousands of cycles.

Key Features

• 3.75-inch D2 tool steel dagger blade with superior edge retention
• Stonewashed aluminum handle construction for lightweight durability
• Double-action out-the-front firing mechanism
• Integrated glass breaker for emergency situations
• Removable pocket clip for secure everyday carry
• Plain edge configuration optimized for tactical cutting tasks
• Ambidextrous operation suitable for left or right-handed users

Field testing demonstrates the CTK-1's reliability across temperature ranges and extended use cycles. The D2 steel blade maintains sharpness through rope cutting, cardboard breakdown, and general utility tasks without frequent resharpening. Law enforcement and military personnel appreciate the glass breaker feature for vehicle extractions, while the secure locking mechanism prevents accidental deployment during carry.
