CobraTec Large FS-3 Carbon Fiber Automatic Knife

The CobraTec Large FS-3 Carbon Fiber LCFFS-3DNS automatic knife is a full-size OTF model that combines an aggressive dagger design, a lightweight carbon fiber handle, and a reliable automatic mechanism for everyday and tactical use.

The FS-3 is one of the most distinctive OTF knives in the CobraTec lineup, and in the Large version it offers full-size dimensions suitable for more demanding use as well. The Carbon Fiber variant gives the knife a modern look while also reducing weight without sacrificing strength.

The defining feature of the knife is its dagger blade measuring approximately 8–9 cm (approx. 3.25–3.5″), designed for maximum penetration and symmetrical performance. This profile is ideal for tactical use as well as precise cutting.

As soon as you take the knife in hand, the combination of lightness and solidity stands out immediately. The carbon handle feels premium while also ensuring a secure grip even during extended use.

The blade is made from D2 tool steel, which offers good hardness, long edge retention, and solid wear resistance. This material is a proven standard in the EDC knife category.

Operation is handled by a double-action OTF mechanism, allowing fast one-handed deployment and retraction of the blade using a sliding button. The mechanism is designed for smooth and reliable action.

The construction also includes a pocket clip for secure carry and a glass breaker, expanding the knife’s usefulness in emergency situations.

The knife comes in typical CobraTec packaging and is covered by the manufacturer’s lifetime warranty.
