Knives and ancillary items for butchers
  The next step in the manufacturing process, the hardening process, is crucial to the quality of the knife. The blanks are hardened in a protective gas atmosphere in continuous operation at temperatures exceeding 1,000°C. The equipment used at Friedr. Dick meets the current state of the art and guarantees a defined and controlled hardening process. Any contact with oxygen is avoided to prevent surface oxidation since this would necessitate subsequent grinding under high contact pressure and thus heating of the blade, which can lead to embrittlement.

  The next process stage is so-called tempering. As the hardened steel is inelastic, tempering at temperatures between 200 and 280°C eliminates the greatest internal stress within the steel, i.e. the molecules in the steel are “aligned”. This imparts the required ductility and strength to the blades.

  Our blade is used for cutting meat and poultry.
