A "legend" has returned. The 4-part Mercator pocket knife was produced more than 60 years ago by the Kaufmann und Söhne Company in Solingen. We have brought the knife back to life based on faded yellowing drawings. It is built to include 4 tools, just like in the olden days. A lockable knife blade, the awl for loosening knots and punching holes into leather and fabrics, the can opener, and a corkscrew. It takes more than 120 work processes for its manufacturing. Everything is crafted by hand. The awl and the can opener are forged on belt drop hammers, rough-ground and then finally fine-ground. The core in the corkscrew helix prevents the "crumbling" of the cork. The blade is made of carbon steel which holds its edge well, is sharpened and then receives another dry-fine grind. The handle, made of blued steel, doesn't have the non-rust properties of modern coatings, but it gives the knife a high-quality appearance. All these are properties that can hardly ever be found in the knives of today. The blade steel is C75 carbon steel. We recommend our matching knife holster in the following colours: Natural             Black             Dark brown

The small knife from the Mercator series has the same properties as its big brother, but it is not lockable. The blade is optionally available in stainless steel or in carbon steel. The robust powder-coated metal handle is available in two colour variations, in the classic black or in blue. Thanks to its flat design, the small Mercator is a handy knife that could fit into pretty much any trouser pocket.
