Which hammer is designed to prevent rebound with lead shot inside its head?

The dead blow hammer is designed specifically to minimize rebound when striking a surface. It accomplishes this through the use of a hollow head filled with lead shot. When the hammer strikes an object, the shot inside shifts and absorbs some of the energy, reducing the force that causes the hammer to bounce back after impact. This feature is especially useful in situations where precise strikes are required, such as in automotive applications or carpentry, as it allows for greater control and less risk of damaging the workpiece or the tool itself.

In contrast, other types of hammers, such as the rawhide, brass, and ball peen hammers, do not incorporate this design principle. Rawhide hammers are made of soft materials to prevent marring surfaces, brass hammers are used where non-marring metallic strikes are needed, and ball peen hammers are designed for shaping metal and striking chisels, all of which do not feature the lead shot design for minimizing rebound.
