CRKT Monument Liner Lock 4000 Folding Knife

CRKT Monument Liner Lock 4000 is built on the philosophy of simplicity, practicality, and elegant minimalism. It is not a heavy-duty work knife, but a compact tool designed to be comfortable for everyday carry while still looking refined.

The character of the model is based on a slim construction, clean lines, and a practical Liner Lock. The knife does not try to impress with unnecessary complexity — its strength lies in functional, well-usable design.

The Monument philosophy is to offer an unobtrusive, elegant, and practical EDC knife that is easy to carry and ready for everyday cutting tasks.

CRKT Monument 4000 is intended for users who prefer discreet design, compact dimensions, and practicality over a robust or tactical appearance.

• Elegant minimalist design – clean lines and a discreet appearance.
• Compact construction – comfortable everyday carry in a pocket. 
• Liner Lock – reliable blade lockup in the open position. 
• Practical blade – versatile for common cutting tasks. 
• One-handed operation – comfortable and quick handling. 
• Ergonomic handle – secure grip and good control during use. 
• Low profile – the knife feels unobtrusive in a pocket and does not take up unnecessary space. 
• Practical pocket clip – safe and convenient carry. 
• Versatile EDC use – suitable for work, home, and travel. 
• Timeless look – combines practicality with elegant design. 

Compact construction – may not suit users who prefer larger and more robust folding knives.

EDC focus – intended mainly for common cutting tasks, not for heavy-duty work. 

Liner Lock – with an incorrect grip, a finger may contact the locking mechanism. 

Slim construction – does not provide the same level of robustness as more massive work-oriented models. 

Mechanism maintenance – moving parts should be kept clean and lightly lubricated as needed. 

Not intended for prying – the knife should not be used as a pry bar, chopper, or impact tool. 

Discreet design – users looking for a bold or aggressive-looking knife may find it too simple. 

Limited for demanding tasks – the compact design is an advantage for EDC, but also a limitation for rougher work.

• Blade cleaning: After use, wipe the blade with a soft cloth and remove any dirt.
• Drying: Always dry the blade thoroughly after contact with water. 
• Blade protection: For longer-term storage, the blade can be lightly treated with a quality knife oil. 
• Liner Lock maintenance: Keep the mechanism clean and regularly check that it functions properly. 
• Lubrication: Lightly lubricate moving parts with a suitable oil as needed. 
• Checking screws: Occasionally check the tightness of the pivot, handle, and pocket clip. 
• Sharpening: Keep the edge maintained regularly with a quality sharpening system. We recommend Spyderco Tri-Angle Sharpmaker Complete Sharpening System 204MF. 
• Careful use: Do not use the knife for prying, chopping, or as an impact tool. 
• Storage: Keep the knife clean and dry, ideally away from high-humidity environments. 

Regular maintenance will help preserve smooth operation, a sharp edge, and the overall appearance of the knife over the long term.

CRKT Monument Liner Lock 4000 is especially suitable for users looking for a slim, elegant, and practical folding knife for everyday carry.
