The term 'Big Hammers' can be summarized as a type of sledgehammer, which is a tool used for pounding or driving nails into wood or other materials. Sledges are large, heavy hammers with a long handle and a flat head, usually made of metal. They are used for driving stakes, breaking up rocks, and other heavy-duty tasks. Big Hammers are larger and heavier than regular sledges, making them ideal for more demanding jobs.
