Dead-blow hammers are non-marring and come in handy when
you want to reduce back-lash (or back-bounce) of a hammer.
These hammers have a non-sparking soft face and no exposed metal.
The soft face prevents marring of surfaces or equipment. 
Dead blow function uses steel shot. 
A steel reinforced handle provides added strength and safety, and resists breaking on overstrike.
