What is avantages and disadvantages of using planishing?

Planishing, a metalworking technique that involves smoothing and shaping metal surfaces, offers several advantages. It enhances the surface finish, improving aesthetics and reducing the need for further polishing. Additionally, it can strengthen the metal by refining its grain structure. However, disadvantages include the requirement for skilled labor and the potential for distortion if not done carefully, as well as limitations in thickness and material types that can be effectively planished.
