CobraTec Large FS-3 Black OTF Knife
CobraTec Large FS-3 Black is a Large OTF knife with a D2 steel blade and an aluminum handle. The FS-3 model uses a dual action mechanism, so the same control extends and retracts the blade.
Detailed product description
CobraTec Large FS-3 Black belongs to a line of OTF knives designed for everyday carry as well as quick deployment in situations where fast one-handed handling matters. The construction is based on an aluminum handle made from a quality alloy and a D2 tool steel blade, which is standard for this model line.
The FS-3 series is built around a dual action mechanism. The same sliding control is used to extend and retract the blade, contributing to intuitive operation. For this series, the manufacturer also lists a pocket clip, a glass breaker for emergency use, and an included nylon sheath.
The Large size offers a fuller grip and a longer blade than the smaller variants within the same series. The black finish looks restrained and purposeful, so the model fits well into the category of tactical and utility OTF knives.
Character and philosophy
The FS-3 is conceived as a practical OTF knife with an emphasis on fast operation, a secure grip, and everyday usability. In the Large version, it targets users who prefer a bigger knife format, a fuller handle, and more confident handling.

Maintenance and care
