CobraTec CTK-1 Large OTF Dagger — 3.75" D2 Steel Blade, NYPD Blue Aluminum Handle, Glass Breaker & Pocket Clip (Model LNYCTK1DAGNS | UPC 099654025149)
Cutting-edge deployment, tactical edge geometry, and premium materials combine in the CobraTec CTK-1 Large OTF Dagger — a purpose-built out-the-front automatic knife engineered for speed, strength, and everyday readiness. Featuring a 3.75-inch D2 tool-steel dagger blade, a rugged NYPD Blue anodized aluminum handle, an integrated tungsten glass breaker, and a secure pocket clip, this large CTK-1 is ideal for collectors, first responders, EDC enthusiasts, and anyone who wants a high-performance OTF designed to hold up in the field.
Precision Deployment — Dual-Action OTF Performance
The CTK-1 Large uses a dual-action out-the-front mechanism for lightning-fast one-handed deployment and retraction. The ambidextrous slide is smooth, positive, and engineered for repeatability so the blade extends and retracts reliably under real-world stress. The mechanism’s precision tolerances deliver confidence-inspiring operation every time you need instant access.
Blade: Tactical Dagger Geometry + D2 Tool Steel
At the heart of this knife is a 3.75" dagger-style blade crafted from D2 tool steel — a high-carbon, high-chromium tool steel prized for exceptional edge retention and wear resistance. The dagger profile offers symmetrical double-edged strength with superior tip durability and piercing capability, while the plain-ground finish provides clean cuts, easy maintenance, and consistent performance across demanding tasks.
Handle: Aircraft-Grade Aluminum in NYPD Blue
The ergonomically contoured handle is machined from aircraft-grade aluminum and finished in an eye-catching NYPD Blue anodize. Textured milling and subtle jimping deliver a secure, non-slip grip even when wet or gloved, while the robust construction keeps overall weight down without sacrificing strength. The handle’s profile is balanced for control during precision work and comfortable for extended carry.
Rescue-Ready Glass Breaker & Carry Convenience
Integrated at the handle butt is a tungsten carbide glass breaker, offering emergency egress capability for first responders or everyday rescue situations. A stout stainless-steel pocket clip provides secure tip-down carry and quick access; the clip is recessed and robust enough for frequent on-and-off use. A nylon sheath is often included (depending on packaging) for additional carry options.
Built for Durability and Field Use
CobraTec’s CTK-1 Large is engineered to withstand hard use. D2 blade hardness and the anodized aluminum handle resist corrosion and wear, while internal components are designed for longevity. The dual-action OTF mechanism is serviceable and constructed for smooth operation across thousands of cycles.
