585,67 €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.
Herring Brass, Black from Extrema Ratio is a symbol of history and heroism. Its original name is Fairbairn-Sykes or Commando Dagger, and its history is closely associated with British commandos during World War II. This dagger became famous thanks to the young soldiers of the 1st Reconnaissance Squadron "Folgore", who were equipped with this weapon during Operation Herring. Their courage and sacrifice wrote an important page in Italian history. Extrema Ratio has paid tribute to this dagger by preserving the original design, but using state-of-the-art manufacturing techniques. The unique handcrafted finish of the Handle mimics the aging of the brass, giving the dagger a look reminiscent of the original. The dagger was developed in cooperation with the 185th RRAO and adopted as a ceremonial commemorative dagger to mark the 20th anniversary of the regiment's founding and the 75th anniversary of the Herring mission. Both versions (Herring and Herring NE) come with a polymer case with historic Squadrone F frieze, a leather / kydex sheath with brass tip and two commemorative scrolls. Herring Brass, Black is not just a knife, it's a part of history that lives on in every piece. Join the ranks of those who appreciate history, quality and style. Choose Herring Brass, Black.
