Hammer sheet metal into rough shapes using these forming bags as a stabilizing base. Made of leather for durability, they are often used to initially form sheet metal before it is finished on a solid surface such as a forming block, dolly, or anvil.

Tabletop bags are unfilled. Fill them with sand or No. 9 lead shot (sold separately), which conforms to shapes better. The filling needs space to shift as these bags are used for forming, so leave some room in the bag.
