Mercator Knife: The Pocket Knife Classic
The Mercator knife is a legend among pocket knives and a true classic of Solingen knife design. It was designed in Solingen in 1867 at the knife and blade smithy Indiawerk Heinrich Kaufmann & Söhne, where it was hand-produced in large numbers for many years.
Handcrafted from High-Quality Materials
For over 150 years, the Mercator knife has been produced almost unchanged in Solingen, Germany. Since 1995, the Mercator brand has been part of OTTER-Messer, and the knives are still meticulously handcrafted in our factory today, maintaining the highest standards of quality. Thus, Mercator and OTTER-Messer are closely connected—not only through the Otter logo embossed on the knife handle.
Mercator or Kaiser Wilhelm Knife?
The Mercator knife is also known as the Kaiser Wilhelm knife. Although it was not originally designed as a military knife, Kaiser Wilhelm's soldiers quickly appreciated the qualities of the Mercator knife. It became an essential tool at the front. This is where the colloquial name "Kaiser Wilhelm Knife" originates. Many soldiers from both World Wars relied on this versatile pocket knife. However, it was never an official army equipment item.
From Germany to the World
After World War II, American soldiers brought the Kaiser Wilhelm knife to the USA. There, too, the pocket knife quickly gained popularity. However, it gained a rather notorious reputation: from a practical lifesaver and all-round knife in the 1960s and 1970s, the Mercator knife became the most commonly used weapon in the infamous Bronx neighborhood of New York City. Today, the Mercator knife is a reliable companion for travel and outdoor activities worldwide. It is also a favored tool in the household, DIY, and crafts, thanks to its robustness.
Functional, Reliable, Robust, and Indestructible
Then as now, the Mercator knife impresses with its characteristics. It is:
- functional,
- compactly slim,
- reliable,
- extremely robust, and
- nearly indestructible.
The Classic Reimagined
Functional, robust pocket knives don’t have to sacrifice elegant, modern appeal. In addition to the traditional designs of the Mercator knife, our online shop offers new models that, for example, vary in color from the well-known classic while preserving the classic Mercator silhouette. With its tried-and-true slim handle and classic blade shape, the outdoor knife remains true to its historical line even in modern design.
Materials like brass, copper, and Damascus give the new Mercator knives a special charm. Now equipped with a stainless steel clip, the new Mercator from OTTER-Messer is even more functional and practical: whether on a belt, pocket, or backpack—thanks to the clip, your knife is always within reach. A must-have not just for outdoor enthusiasts!
