A Ball Peen Hammer is a versatile hand tool that is commonly used in metalworking and construction applications. It features a flat striking surface on one end and a rounded, ball-shaped peen on the other. The peen is typically used to shape, flatten, or expand metal, while the flat surface is used for general striking and pounding tasks.

These hammers come in various sizes, weights, and handle materials, depending on the user's needs. They are commonly made with a steel head and a durable handle, such as wood or fiberglass. Some Ball Peen Hammers also feature a non-slip grip for better control and comfort during use.
