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.

Attilio “Atti” Morotti, born in Bergamo in 1957, is a highly regarded craftsman and knife maker. His passion for craftsmanship began with his work in a mechanical workshop, and led him to create his own brand of knives, Atti Knives. In addition to being a craftsman, Morotti is also an avid motorcyclist who has traveled many of the roads of Italy and Europe. His interest in knives began when he visited a knife-making exhibition, where he was fascinated by the mastery and quality of the work on display. This experience inspired him to create his first fixed blade knife in 2002. Despite his lack of formal training, through determination and a love of craftsmanship, Morotti was able to create knives of recognized quality. His skills earned him the title of “Master of the Italian Knife Guild” in 2007. Atti Knives are true works of applied art. Morotti starts with simple sketches, which are then refined with the utmost attention to detail. He uses a variety of materials, such as stainless steel, damascus steel, mother-of-pearl, mammoth fossils and stabilized wood. Each piece is unique, ensuring a truly artisanal design
PTC (Polyhedral Tungsten Carbide) - a flexible type of tungsten carbide that outperforms steel in terms of edge durability. Thanks to a new technology called StaySharp™, it has become possible to produce blades with a hardness of 71HRC, which translates into incredibly long sharpness retention. Made with StaySharp Technology™, the blades remain flexible and are not brittle. Thanks to the unique properties of carbide, they retain a clean, sharp cutting edge longer than traditional steel blades. These properties make the material ideal for knife blades. And with an exceptional hardness of 71 HRC, simply put, they are the hardest and most durable blades ever produced.
W-Lock - innovative wedge locking system. The two-way lock secures the blade in the open position. Closing the knife is done by moving the backspacer backwards, which eliminates accidental unlocking of the blade.
Blade - sheepfoot type with full flat grind (Full Flat Grind). A novelty is the raw finish (Matted) - its striking appearance was achieved by PTC grinding with fine diamonds. Unlike a steel blade, the PTC blade is completely rustproof, making it suitable for both fresh and salt water. Ball bearing ceramic supports the smooth opening of the blade, which can be opened via a hole in the wedge (thumb hole). As a result, it can be easily used by both right- and left-handed people. The whole thing is locked with an innovative W-Lock.
Handle - grips made of Fat Carbon composite, a material of exceptional strength and aesthetics. The backspacer is part of the W-Lock locking system. The decorative pivot contrasts beautifully with the color of the grips. The fore finger groove, made on the front, improves grip security by creating a guard that prevents the hand from slipping on the blade.
Additional accessories - a sheath for the knife made of high-quality leather.
