This two-sided hammer is used for a metalworking technique that involves finishing the surface by finely shaping and smoothing sheet metal. This is done by hammering against a shaped surface while held in a vise or against an anvil. Alternatively, planishing may be done using an English wheel. Planishing tools have steel faces that will stretch your metal, allowing you to shape and smooth gold, silver, brass, stainless steel, and other metals. The lightweight wood handle is easy to grip and works with the weighted head, which is easy to control. To protect your work bench and other surfaces, it’s best to work on anvils or in vises.
