CobraTec Large FS-3 Stonewash is a large-format OTF automatic knife with a D2 steel blade and a high-quality aluminum alloy handle. The model uses a dual action mechanism, meaning the blade is deployed and retracted using a single control.
Detailed product description
CobraTec Large FS-3 Stonewash is an OTF automatic knife designed for users looking for a larger work and EDC knife with fast operation. In the Large version, it offers an overall length of 9" and a 3.5" blade, with a construction based on a high-quality aluminum alloy handle and a D2 tool steel blade.
The FS-3 series uses a dual action mechanism, so the blade deploys and retracts using the same sliding switch. For this model 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 FS-3 is suitable for users who prefer a fuller grip and a more substantial knife in the pocket or gear setup.
