CobraTec Large FS-3 Winter Digi Automatic Knife

CobraTec Large FS-3 Winter Digi is a knife built on a combination of robustness, functionality, and a distinctive outdoor design. Its philosophy lies in offering a durable automatic knife that combines practical materials with fast and intuitive handling.

The Dual Action OTF mechanism, D2 steel blade, and aluminum handle create a construction focused on reliable everyday use. The Winter Digi camouflage gives the model a distinctive character and reflects its outdoor orientation.

FS-3 Winter Digi is intended primarily for users looking for a robust, functional, and visually striking knife, where construction and unique appearance are equally important.

Dual Action OTF mechanism – the blade can be quickly deployed and retracted using the control mechanism.

D2 steel blade – good wear resistance and long-lasting edge retention. 

Durable aluminum handle – strong construction while maintaining reasonable weight. 

Winter Digi camouflage – a distinctive outdoor look. 

Integrated glass breaker – a practical additional feature at the end of the handle. 

Robust construction – suitable for more demanding conditions and practical use. 

Total length of 22.9 cm – offers a good balance between compactness and blade size. 

Distinctive character – also suitable for collectors and fans of tactical design.

Higher weight – approx. 221 g – the knife is more noticeable in the pocket than lighter EDC models.

D2 steel is not fully stainless – in contact with moisture, it requires regular cleaning and corrosion protection. 

The OTF mechanism is more sensitive to dirt than a classic manual folding mechanism and requires regular maintenance. 

The aluminum handle is durable, but cosmetic scratches may appear with hard use. 

The Winter Digi design is bold and may not suit users who prefer a simple or discreet look. 

The glass breaker increases the knife’s length and weight and may be less comfortable to carry. 

Legal restrictions – carrying and using automatic knives may vary in different countries and situations according to applicable regulations.

After use, clean the blade from dirt and dry it thoroughly.

 Regularly treat the D2 steel with a thin layer of a suitable protective oil, especially after contact with moisture. 

Keep the OTF mechanism clean and protect it from dust, sand, and other debris. 

 Lubricate moving parts of the mechanism lightly as needed with oil intended for knives and fine mechanics. Do not use excessive amounts of oil. 

Clean the aluminum handle with a soft cloth and mild cleaning agent. Avoid harsh chemicals. 

 Keep the glass breaker clean and check its attachment. 

 Store the knife in a dry place, ideally away from long-term humid environments. 

 Maintain the edge regularly with a suitable sharpening system. We recommend Spyderco Tri-Angle Sharpmaker Complete Sharpening System 204MF.

Everyday carry (EDC) – for users who prefer a robust automatic knife.

Outdoor and hiking – for common practical tasks in nature. 

Work and practical use – the durable D2 blade can handle a wide range of everyday tasks. 

Lovers of tactical design – Winter Digi camouflage gives the knife a distinctive character. 

Knife collectors – an interesting combination of OTF mechanism, D2 blade, and specific design. 

Users who appreciate extra features – the integrated glass breaker expands the knife’s practical possibilities.
