The CobraTec CTK is a 12.75" out-of-the-front (OTF) knife built for fast, reliable deployment in the field or on duty. With a part-serrated D2 steel blade, this knife combines the edge-holding performance of a quality stainless alloy with the practical versatility of serrated teeth for slicing through tough materials—cordage, webbing, seatbelts, and more. Whether you're a first responder, tactical operator, survivalist, or outdoor professional, an OTF knife that opens hard and fast matters when seconds count.
The stonewashed aluminum handle is durable and lightweight, designed to feel solid in your hand without unnecessary weight. A integrated glass breaker gives you one more tool in a compact package, useful if you ever need to escape a vehicle or breach glass in an emergency. The pocket clip keeps your knife accessible and secure, whether you're carrying it daily or stashing it in a pack for backcountry work.
CobraTec Knives has built a reputation for OTF knives that function like they're supposed to—no gimmicks, no wobble, just reliable deployment. The CTK-12.75" is no exception: a straightforward, no-nonsense blade for users who expect their gear to work the first time and every time.

Frequently Asked Questions
What is an OTF knife and when would I use one?
An out-of-the-front (OTF) knife deploys by pressing a button or lever, shooting the blade straight forward from the handle. OTF knives are popular with first responders, tactical professionals, and outdoor users who need one-handed, speed-of-light blade deployment. Check your local and state laws—OTF legality varies by jurisdiction.
What's the difference between a full serrated and part-serrated blade?
This knife has a part-serrated blade, meaning a portion of the edge is serrated (saw-tooth) and the remainder is straight. Part-serrated designs give you slicing power for cordage and tough cuts alongside the general-purpose edge of a straight blade, making them more versatile in the field.
Is the glass breaker tool really useful?
Yes. A glass breaker concentrates force on a small point, making it much easier to shatter tempered vehicle windows or other safety glass in an emergency. It's one of those "hope you never need it" tools that's genuinely valuable when the moment arrives.
What makes D2 steel a good choice for a tactical knife?
D2 is a tool steel known for excellent edge retention and durability under hard use. It's tougher and holds an edge longer than most stainless steels, making it a solid choice for a working blade that takes real abuse.
