Kavalttaminen

Kavalttaminen is a Finnish term that refers to the act of bending or shaping metal, typically by striking it repeatedly with a hammer. This process is a fundamental technique in blacksmithing and metalworking, used to create a wide variety of objects, from tools and weapons to decorative items and structural components. The process involves heating the metal to a malleable temperature, usually in a forge, and then using a hammer and anvil to impart the desired shape. The force and angle of the hammer blows, as well as the type of hammer and anvil used, all influence the final form of the metal.

Different types of blows can be employed during kavalttaminen, such as drawing out, which lengthens the metal, or upsetting, which thickens it. Flattening, bending, and twisting are also common techniques. The skill of the smith lies in their ability to control the metal's movement and achieve precise shapes through careful hammering. This requires a deep understanding of the material properties of the metal and the thermal dynamics of the heating and cooling process. Kavalttaminen is a time-honored craft that has been practiced for millennia, evolving with advancements in metallurgy and toolmaking. It remains a vital skill for artisans and craftspeople who work with metal.
