CobraTec Large FS-3 Winter Digi OTF Knife

The CobraTec Large FS-3 Winter Digi is a robust OTF knife with a Dual Action OTF construction, which allows the blade to be both deployed and retracted using the mechanism located on the handle. The model stands out with its distinctive Winter Digi camouflage, giving the knife a unique outdoor look.

The blade with a length of 8.9 cm is made from durable D2 steel, which offers good wear resistance and long edge retention. The handle with a length of 12.7 cm is made from a quality aluminum alloy, combining strength with a favorable weight.

The overall length of the knife is 22.9 cm and the weight is approximately 221 g. Another practical feature is the integrated glass breaker at the end of the handle. Thanks to its robust construction, OTF mechanism, and striking camouflage design, the FS-3 Winter Digi is an interesting choice for users looking for a durable and distinctive OTF knife.

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

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

Durable aluminum handle – solid construction while maintaining a reasonable weight. 

Winter Digi camouflage – 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. 

Overall 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 – more noticeable in a pocket than lighter EDC models.

D2 steel is not fully stainless – it requires regular cleaning and corrosion protection when exposed to moisture. 

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

The aluminum handle is strong, but cosmetic wear may appear during 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 make carry less comfortable. 

Legal restrictions – carrying and using automatic knives may vary by country and situation 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 suitable protective oil, especially when exposed to moisture. 

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

 Lightly lubricate moving parts of the mechanism 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 a gentle cleaning agent. Avoid aggressive chemicals. 

 Keep the glass breaker clean and check that it is securely attached. 

 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 OTF knife.

Outdoor and hiking – for common practical tasks in nature. 

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

Tactical design fans – the Winter Digi camouflage gives the knife a striking character. 

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

Users who appreciate additional features – the integrated glass breaker expands the knife's practical options.
