What type of hammer is primarily used to correct small indentations or dents in containers?

The primary tool used to correct small indentations or dents in containers is a rubber mallet. A rubber mallet is specifically designed to deliver a soft blow that can adjust minor deformities without causing additional damage to the surface of the container. This is crucial when working with containers made from materials that can be easily scratched or dented, as a harsher tool could exacerbate the problem.

Using a soft, rubber-ended tool allows for effective correction of minor dents while preserving the integrity of the container. It is ideal for ensuring that the surface remains smooth and functional, which is essential for maintaining the structural integrity and aesthetics of intermodal containers. In contrast, other hammers, such as a ball-peen hammer or small sledge, could potentially damage the container material. A claw hammer is not suitable for this task as it is designed primarily for pulling nails and can easily leave unwanted marks or damage. Therefore, a rubber mallet stands out as the most appropriate choice for this purpose.
