CobraTec Large FS-X Gen III Automatic Knife
Detailed product description
The CobraTec Large FS-X Gen III is an automatic knife intended for users looking for a quickly accessible working knife or backup knife with one-handed operation. Structurally, it is based on the FS series concept, which, according to the manufacturer, combines an aluminum handle, a pocket clip, and a dual-action mechanism controlled by a sliding switch.
In practice, this means simple and straightforward operation when opening and closing the knife without the need to change your grip. The Large version is aimed at users who prefer a full-size knife in the hand. The Gen III designation suggests a newer generation of the model line.
Character and philosophy
The FS model line focuses on fast automatic deployment, simple one-handed operation, and practical carry. In the Large size, it makes sense especially for users who prefer a more secure grip and a more robust format than more compact variants.

Higher purchase price compared to basic automatic knife models.
The OTF mechanism requires regular maintenance and cleaning to remain reliable and smooth.
D2 steel is not stainless – when used in humid environments, it is advisable to pay attention to protecting the blade from corrosion.
More robust construction may mean greater weight and larger dimensions compared to compact models.
The automatic mechanism is not intended for rough handling or use as a pry bar or impact tool.
Legal restrictions – the carry and use of automatic knives may vary depending on the specific country or situation.
Maintenance and care
After use, clean the blade from dirt and dry it thoroughly.
Treat the D2 steel regularly 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 contaminants.
Lightly lubricate moving parts of the mechanism as needed with oil intended for knives and fine mechanics. Do not use excessive amounts of oil.

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.
