For over a century, the Mercator knife has been crafted in Solingen, Germany, maintaining its original design and renowned quality. Initially produced by the "Mercator" Indiawerk Heinrich Kaufmann & Söhne, this Solingen original quickly gained a reputation for its exceptional qualities. Known as the "Kaiser Wilhelm Messer" during that era, its near-indestructible nature meant it was often passed down through generations, ensuring its enduring legacy.

Since 1995, OTTER-Messer in Solingen has continued the production of this robust pocket knife. Its classic shape and core qualities – reliability, robustness, and handiness – remain unchanged, making it a trusted companion for everyday tasks and outdoor adventures. While new models offer colour variations, they consistently retain the iconic Mercator silhouette.

The Mercator Junior Pocket Knife offers the same dependable performance as its larger counterpart, but in a compact, non-locking design. Its flat profile makes it an exceptionally handy knife, easily fitting into a pocket, ideal for those who appreciate a reliable tool for fishing, hunting, or general outdoor use.

To maintain the carbon steel blade, regular cleaning and oiling are recommended to prevent rust and ensure its longevity.
