- Flipper Natural Micarta, Acid Stonewashed N690Co – A sophisticated folding knife by Jens Ansø. Natural Micarta and Acid Stonewashed N690Co steel create a harmonious, raw elegance. A solid, reliable choice for collectors and connoisseurs.

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.

Jens Ansø, a Danish industrial designer and knife maker, began his career in 1988. He founded ANSØ of DENMARK in 2001 and is known for the flowing lines, harmony and perfection of his work. His knives, both fixed and folding, reflect an extraordinary attention to detail and soft shapes. He has collaborated with companies such as Spyderco, Böker and Fox Knives, and his designs have been mass-produced. Anso is also valued for his use of exclusive materials and innovative approach to design.
N690Co - rich in cobalt 1.65% (Co), corrosion-resistant, high-carbon 1.07% (C), martensitic chromium steel 17.30% (Cr) with molybdenum 1.10% (Mo) and vanadium 0.10% (V). Developed to provide better wear resistance compared to the original Böhler N690 steel, but with a higher cobalt (Co) content. It is characterized by extremely high corrosion resistance and long edge retention. One of the best tool steels in the world today. Hardened to 59-61 HRC. Manufactured by Böhler Edelstahl in Kapfenberg, Austria.
Blade – Sheepfoot blade with Acid Stonewashed finish, which effectively masks fine scratches caused during use. The thin blade combined with the high, flat grind (Flat Grind) ensures excellent cutting edge geometry and exceptional cutting performance. The opening mechanism works smoothly and precisely. The blade can be opened with a flipper (index-finger flipper). When unfolded, the flipper forms a mini guard, preventing the hand from accidentally slipping onto the blade. A liner lock mechanism is used to ensure safety and stability during operation.
Handle - Grips made of Micarta composite, a lightweight material resistant to weather, chemicals and mechanical damage. The characteristic surface treatment called “Ansø texture” ensures excellent grip and control of the tool. The solid backspacer reinforces the structure, ensuring adequate rigidity and strength. The simplicity and robustness of the construction guarantee reliability for many years of use. The single-position clip (right), made of stainless steel, allows the knife to be carried in the tip-up position.
Accessories – The set includes a zippered soft nylon pouch with the manufacturer's logo for safe storage and transportation of the folder.
