Pfeile cresting is a process of forming decorative patterns on metal surfaces. It is a form of cold forging, where thin metal sheets are heated and given a particular shape by hammers and other tools. The resulting product is often used in jewelry and architectural applications, such as on gates and churches. The techniques used to create the shape, such as hammering, rolling and filing, date back centuries. Pfeile cresting is often used to accentuate surface features, such as ornamented edges, textures, and rigid and curved lines. It usually requires several skilled workers and involves a number of processes, such as forming, cutting, and hammering the metal sheet to create the desired shape. The end result is usually a polished and elegant effect that adds an extra layer of sophistication to any metallic surface.
