CobraTec CTK-1 Large 3.75" OTF Dagger, D2 Steel Blade, Carbon Fiber Aluminum Handle, Glass Breaker & Pocket Clip

The CobraTec CTK-1 Large OTF dagger brings serious edge to your truck, your pack, or your EDC rotation. At 3.75 inches, this out-the-front blade opens fast and deploys with authority—the kind of knife that earns respect on the workbench, in camp, or wherever you need a reliable cutting tool that doesn't waste time. Built on a D2 steel blade paired with a carbon fiber aluminum handle, the CTK-1 splits the difference between durability and weight, giving you a blade that holds an edge without dragging down your gear.

OTF knives live in a unique space: they're tactical-minded, quick-deploying, and engineered for serious users. The CTK-1 fits that bill without the theatrical hype. The plain blade profile cuts, slices, and handles utility work without flourish, and the dual-material handle—carbon fiber reinforced aluminum—resists the wear that comes from real use. A glass breaker on the pommel adds an emergency function, and the integrated pocket clip keeps the knife accessible without falling out of your pocket.

Whether you're a knife enthusiast, a working professional, or someone who appreciates a well-made tool that shows up when you need it, the CTK-1 is built to perform. D2 steel is forgiving enough for field maintenance and tough enough for hard use, making it a dependable choice for hunters, overlanders, and anyone who carries a knife seriously.

Frequently Asked Questions

What is an OTF knife and how does the CTK-1 deploy?

OTF stands for out-the-front—the blade launches and retracts in line with the knife's body. The CTK-1 is a dagger-style OTF, meaning the blade runs straight through the center of the handle and deploys forward when you actuate the mechanism. It's fast, direct, and purpose-built for users who want a blade ready without fumbling.

Is D2 steel easy to maintain in the field?

D2 steel strikes a good balance: it holds an edge well and is forgiving enough to sharpen without specialized equipment. You can touch it up with a portable whetstone or steel in camp or at home without the fussiness of stainless or premium super-steels.

Can I carry the CTK-1 in my pocket?

Yes. The CTK-1 includes an integrated pocket clip designed to keep the knife secure and accessible in a pants or shirt pocket. The clip holds it reliably during normal movement and activity.

What does the glass breaker do?

The glass breaker is a hardened point on the pommel (back end) of the knife. It's designed to break automotive or emergency glass quickly in a crisis situation, adding a practical safety function to the tool.
