This product is intended for use only by adults with knowledge and experience in handling sharp cutting tools. Improper use of the knife can result in serious injuries. The blade is extremely sharp and can easily cut through skin and tissue; therefore, extra caution should always be exercised while cutting, and hands should be kept away from the cutting edge. To prevent the knife from slipping, it is recommended to cut on a stable, non-slip surface and avoid excessive force, which may cause uncontrolled blade movement.
Leaving the knife on the edge of a table, countertop, or in easily accessible places—especially where children are present—poses a significant safety risk. The knife should always be properly secured after use, ideally by placing it on a stable surface or storing it in designated knife blocks, protective sheaths, or magnetic strips. The knife should never be used for tasks it is not designed for, such as opening cans or prying objects, as this can damage the tool and lead to dangerous accidents.
A dull blade increases the risk of injury, as it requires more force and is more likely to slip from the material being cut. Therefore, it is essential to sharpen the knife regularly to maintain optimal sharpness. Additionally, proper cleaning and drying of the knife are necessary to prevent corrosion and bacterial growth. Periodic inspection of the handle and blade is recommended to check for cracks, chips, or looseness. If any damage is detected, the knife should be repaired or replaced immediately.
When using the knife, focus solely on the task at hand—avoid talking on the phone, watching television, or other distractions while cutting. Ensure proper lighting in the workspace for better visibility and control. Please note that some countries or regions have laws restricting the ownership and carrying of knives. Before purchasing or using this knife, verify that its use is legal in your location according to applicable regulations.
Following these safety guidelines will help ensure safe and effective knife use, minimizing the risk of accidents and extending the lifespan of the tool.

Civivi - a sub-brand of WE Knife, a company that produces knives of the highest global quality. Production is carried out on the same production lines as WE, so the highest standard of assembly is maintained.
Damascus - Damascus stainless steel blade with a unique pattern. The blade, consisting of two different types of steel, was forged and assembled together in different ways obtaining this amazing pattern. It is characterized by high hardness in the range of 58-60 HRC
Blade - Clip Point type finished with etching highlighting the unique damascus patterns. The expansive belly extends the length of the cutting edge in relation to the length of the blade converging towards the strikingly needle-sharp tip, which is in line with the center of the knife, ensuring maximum effectiveness. The small thickness of the blade combined with a high flat grind (Flat Grind) gives excellent cutting properties combined with high durability. Ball bearing ceramic supports the smooth opening of the blade, which can be opened using either a hole in the blade (thumb hole) or a flipper flipper (index-finger flipper) that acts as a stinger when opened. As a result, it can be easily used by right- and left-handed people. To maintain full control of the blade, there is a notched thumb rest on the back of the upper jimping wedge. The whole is locked with a solid liner lock.
ULTEM™ - a plastic belonging to the Polyethermoids family or simply PEI. This material is characterized primarily by high mechanical and impact strength with a very high strength-to-weight ratio. It is also characterized by high thermal resistance (180⁰C) and high chemical resistance to all kinds of solvents (synthetic and natural), lubricants or other chemicals. Adding to this total insensitivity to weather conditions, we get an ideal material for knife handles.
Handle - grips made of polished, transparent Ultem™ plastic, which were screwed to steel liners. The so-called open-backed design without the typical backspacer, attached to each other with steel spacer sleeves for easy cleaning. The simple, secure design gives assurance of many years of use. The deep-carry, two-position (right/left) clip allows you to carry the knife in tip-up position (tip up).
Case - included zippered soft nylon case with the manufacturer's logo for safe storage and transportation of the folder.
