Non-sparking, uni-cast construction with no exposed metal, soft face yields, does not mar surface or equipment, does not absorb liquids. Dead blow function uses steel shot. Steel reinforced handle resists breaking on overstrike.Uni-Cast construction of non-ferrous materials eliminate sparking and will not absorb liquidsNo exposed metal on face, head or shaftDead blow function eliminates bounceback when striking hardened surfacesSoft face helps to minimize marring and surface damageSteel reinforced handle provides strength and resists breaking on overstrike
