CobraTec Large FS-3 Stonewash OTF Knife
The large CobraTec FS-3 in the Stonewash finish is an ambidextrous model with a D2 steel blade and a high-quality aluminum alloy handle. The dual action mechanism allows the blade to be deployed and retracted using the same control.
Detailed product description
The CobraTec Large FS-3 Stonewash is a larger OTF knife designed for users seeking a secure grip, fast operation, and durable materials in a pocket-sized format. The FS-3 model is built around a high-quality aluminum alloy handle and fitted with a D2 steel blade. The Stonewash version corresponds to the TNS designation in the manufacturer's catalog.
The knife uses a dual action mechanism, meaning the blade extends and retracts via movement of the same control. For the FS-3 series, the manufacturer also lists a pocket clip, a glass breaker for emergency situations, and an included nylon sheath. Thanks to its larger dimensions, the Large version is one of the more practical choices for users who prefer a fuller handle and a longer blade.
This is a straightforward automatic knife for everyday carry where this type of knife is legally permitted. It will appeal to customers who want a combination of rapid deployment, a more robust body, and an easy-to-maintain blade finish.

Maintenance and care
- Keep the blade clean and dry, especially after contact with moisture or aggressive environments.
