The CobraTec Knives CTK-1 Large is a double-action out-the-front knife built around a 3.75-inch tanto blade in D2 tool steel, finished with a partially serrated edge. It carries closed at 5.75 inches and runs 9.50 inches overall when deployed, putting it in full-size everyday-carry territory rather than a pocket-friendly micro design. The Army DigiCamo aluminum handle keeps weight at 9 ounces while staying rigid enough for daily use. This one suits buyers who want fast, one-hand deployment from an OTF action and a blade profile that handles both piercing and general cutting. See more options in our knives selection.
The double-action OTF mechanism fires and retracts the blade from a single slider, so deployment takes minimal effort. D2 steel is a high-carbon, high-chromium tool steel chosen for edge retention and strength, and the part-serrated grind splits the cutting edge between plain and toothed sections for rope, webbing, and harder materials. The tanto point puts more steel behind the tip for piercing tasks. CobraTec builds in a safety feature that stops the blade from fully deploying if its path is obstructed; once it drops into safety mode, you reset it by pulling the blade fully back into its locked position. A pocketed glass breaker on the butt cap handles emergency egress, and the included ambidextrous pocket clip lets you carry on either side.
This knife earns its keep as a daily carry blade for utility cutting, with enough tip strength and serration to back you up in an emergency. The glass breaker and fast OTF action make it a reasonable pick for first responders, drivers, and anyone who values quick access. CobraTec assembles the CTK-1 Large in Texas and backs it with an unconditional lifetime warranty covering repair or replacement. A nylon sheath ships with it for belt or bag carry. Pair it with one of our compact lights for a rounded EDC setup, or browse related accessories while you're here.
Double-action out-the-front means the blade both deploys and retracts using the same slider control. You push the slider forward to fire the blade out and pull it back to retract, all with one hand. The CTK-1 Large uses this design for quick, repeatable deployment without flipping or manual blade adjustment.
CobraTec builds in a safety that prevents the blade from fully deploying if anything obstructs its path. When this triggers, the knife enters safety mode. To restore normal function, pull the blade all the way back into its locked position, which resets the mechanism and makes the OTF action fully operable again.
D2 is a high-carbon, high-chromium tool steel known for strong edge retention and durability. It holds an edge longer than many softer stainless steels, which makes it a solid choice for an everyday-carry blade that sees regular cutting work. The tanto grind on the CTK-1 also adds tip strength for piercing tasks.
Yes. The knife ships with a nylon sheath for belt or bag carry and includes an ambidextrous pocket clip, so you can set it up for left- or right-side carry. It also features a glass breaker on the butt cap for emergency use.
