    Steel is not the same in a spoon as it is in a knife, nor does it cut the same if it hasn’t been properly hardened and tempered.
    Heat treatment can only be applied to martensitic steels, those with enough carbon to react and transform under high temperatures. This achieves the ideal internal structure for a good cut, high strength, and low wear.<\/p>\n<\/div>\n<\/div>\n

    Temple, the first quality test<\/h1>\n

    The tempering process begins by heating the steel to very high temperatures (around 1,060 to 1,100\u00b0C) until it austenitizes, meaning it undergoes internal changes and is ready for transformation. This process demands precision: no more and no less time than necessary.
    Then it is rapidly cooled to room temperature: this “shock” transforms the steel’s molecular structure into martensite, which is much harder and more resistant. This is the first major step in ensuring the blade will cut and withstand the demands of a professional.<\/p>\n

    The resulting hardness not only allows for a clean and long-lasting cut, but also protects against corrosion and maintains strength throughout the knife’s structure, without weak points or areas prone to rust.<\/p>\n

    Tempering: a balance between hardness and strength<\/span><\/h1>\n

    An extremely hard knife can be brittle and break under a blow or intense pressure. That’s why, after hardening, Arcos applies tempering: the steel is reheated (250\u00b0C) to reduce internal stresses, distributing the resistance and preventing the dreaded brittleness.
    This achieves sufficient elasticity for the knife to withstand professional use and cleaning processes without cracking, while maintaining the precise cutting edge demanded by the most discerning users.<\/p>\n

      The knife-making tradition in Albacete, a city that respects steel<\/h1>\n

      Arcos hasn’t forgotten the weight of history. In Albacete, master cutlers used to pray for “good luck” during the tempering process with an old incantation, because they knew that the future of each blade depended on it. Today, automated processes perfect what experience and tradition have taught: that without proper tempering, a knife is worthless, and without proper annealing, it won’t last.<\/p>\n
