Heavy hammers are tools used for pounding and driving objects into the ground. They come in a variety of shapes and sizes, and can be made from different materials. Two examples of heavy hammers are sledges and MAULS. Sledges are large, heavy hammers with a long handle and a flat head, usually made of metal. MAULS are also heavy hammers, but they have a round head and a shorter handle. Both types of hammers are used for driving stakes, posts, and other objects into the ground.
