CobraTec Large FS-3 NYPD Blue Automatic Knife
Detailed product description
CobraTec Large FS-3 NYPD Blue belongs to the OTF knife series 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 states 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 handled by the same switch. Practical equipment is complemented by a pocket clip, a glass breaker for emergency situations, and the included nylon sheath. The NYPD Blue colorway visually distinguishes this model, while its construction is based on the same FS-3 Large platform.
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 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 a suitable protective oil, especially when exposed to moisture.
The OTF mechanism should be kept clean and protected from dust, sand, and other debris.
Lightly lubricate moving parts of the mechanism as needed with oil intended for knives and fine mechanisms. 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.
