CobraTec Large FS-3 NYPD Blue Out-The-Front Knife
The CobraTec Large FS-3 NYPD Blue is a large OTF knife with a D2 steel blade and a high-grade aluminum alloy handle. The model uses a dual action mechanism, features a pocket clip, a glass breaker, and comes with a nylon sheath.
Detailed product description
The CobraTec Large FS-3 NYPD Blue belongs to the OTF knife line designed for fast and direct operation with a single sliding control. In the Large version, it offers a full-size format for everyday carry and quick use, while the manufacturer lists a D2 steel blade and a high-grade aluminum alloy handle for the FS-3 model.
The FS-3 series uses a dual action mechanism, so both blade deployment and retraction are controlled by the same switch. Practical features are complemented by a pocket clip, a glass breaker for emergency situations, and the included nylon sheath. The NYPD Blue colorway sets this model apart visually, while its construction is based on the same Large FS-3 foundation.
This is a knife for users looking for an automatic OTF mechanism, a metal construction, and straightforward operation without unnecessary complexity. Thanks to the Large size, the knife feels more secure in the hand than smaller versions in the series.

Maintenance and care
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 after contact with moisture.
Keep the OTF mechanism clean and protect it from dust, sand, and other debris.

Clean the aluminum handle with a soft cloth and mild cleaner. 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 humidity.
Maintain the edge regularly with a suitable sharpening system. We recommend Spyderco Tri-Angle Sharpmaker Complete Sharpening System 204MF.
