CobraTec Large FS-3 Red OTF Knife

 The FS-3 series is designed as a more robust OTF knife for everyday carry and regular practical use, where quick blade deployment, confident handling, and a durable metal construction come into play. In the Large size, it is aimed at users who prefer a full grip and a longer blade. 

OTF dual action mechanism for blade deployment and retraction using the same control

D2 steel blade according to the manufacturer’s catalog

Handle made of high-quality aluminum alloy

Large construction for a fuller grip

Pocket clip and glass breaker included

Nylon sheath included in the package

This is a larger OTF knife, so it may not suit users who prefer more compact dimensions for discreet everyday carry.

For automatic knives, it is always advisable to check local laws regarding carrying and use before purchase.

The manufacturer does not list blade hardness, blade thickness, or a specific blade finish for this version in the available catalog.

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

 Care for the D2 steel regularly with a thin layer of suitable preservation oil, especially when exposed to moisture. 

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

 Lightly lubricate the 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 mild 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 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 routine tasks. 

Tactical design enthusiasts – the 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.

 CobraTec Large FS-3 Red is a boldly designed large OTF knife with D2 steel, an aluminum handle, and practical accessories. It makes the most sense for those who want a larger automatic model with simple dual action operation.
