CobraTec CTK-1 Large OTF Knife 3.75" D2 Steel NYPD Blue Glass Breaker

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 tactical functionality with premium materials in a compact package that fits standard pocket carry.

What Makes This Different

The CTK-1 stands apart with its D2 tool steel blade that maintains edge retention significantly longer than standard stainless options. The dual-action OTF mechanism fires the blade forward and retracts it with the same thumb slide, eliminating the need for manual blade closure. NYPD blue anodized aluminum construction provides corrosion resistance while keeping overall weight to just 4.2 ounces.

Key Features

• 3.75-inch drop point blade in D2 tool steel with 60-62 HRC hardness
• Dual-action out-the-front mechanism with ambidextrous thumb slide
• NYPD blue Type III hard anodized aluminum handle construction
• Integrated glass breaker tip for emergency situations
• Deep carry pocket clip positioned for tip-up carry
• Overall length of 8.75 inches with 5-inch closed length
• Plain edge blade geometry optimized for utility cutting tasks

Field performance centers on the D2 steel's ability to hold a working edge through extended cutting sessions without frequent resharpening. The drop point profile handles detail work and general utility tasks equally well, while the glass breaker extends functionality for emergency response scenarios. Weather resistance comes from the hard anodized finish that prevents corrosion in humid environments.
