Of the incredible 20,000 different models produced by Lütters & Cie. around 1920, only the most popular models are still in production today.
In addition to fixed special knives for sailors and the fishing industry (fillet, twine, codfish, gut and filleting knives), this mainly includes folding knives without a locking mechanism.
Loewen knives - as it is written in large letters on every blade - are knives for professionals. Around 400 shipyards, ship chandlers, fishing cooperatives, electricians and paper mills are among the main customers. It is a mistake to believe that they are only sought after in Germany. Lütters fillet knives are used to gut fish in Scandinavia as well as in Namibia. And because working knives are not made with perfect workmanship in mind. Small irregularities in the wood and polish correspond to the general quality level of the manufacturer and in no way restrict the function of the knife.
Lütters & Cie. was founded in 1840.
In those days, everything was still done in-house in the factory buildings: the forging of the steel, the adjustment and surface treatment of the handle scales as well as the sharpening and fine polishing of the blade. Nowadays, the blades leave the factory briefly for hardening: it would not be profitable to operate a hardening furnace yourself.
Most people demand knives made of non-stainless carbon steel. These blades are characterized by a very fine structure and great flexibility and can be easily resharpened. However, the highest quality is also ensured for stainless steel blades. After hardening, the blades are deep-frozen for five to eight hours at minus 80 degrees, after which they are tempered again to around 150 degrees. This treatment removes tension from the steel and makes it as flexible as classic carbon steel.
