A standard hammer has a head made of steel which bounces off the nails it hits. A special “dead blow” hammer has a hollow head which is loosely filled with tiny spheres of lead or sand that can rattle around inside the head.

The normal hammer B. The dead blow hammer C. They will both deliver the same force.
