What type of finish gives the appearance of small indentations in the metal?

A hammertone finish is characterized by its unique textured appearance, which resembles small indentations or the look of a hammer's impact on the metal surface. This finish is often used not only for decorative purposes but also to help cover imperfections and provide a more durable coating. The visual effect comes from specific techniques used during application, creating a pattern of raised and recessed areas that catch light in different ways, enhancing the aesthetic appeal.

In contrast, other finishes such as satin and matte provide smooth surfaces without the distinctive dimpled effect, while a gloss finish is polished and reflective, completely differing from the hammertone style. Thus, the hammertone finish stands out for its textured, indented look, making it the correct response to the question.
