Tekton Dead Blow Hammers contain round steel shot inside the head to reduce post-strike rebound and allow for better-controlled hits to the workpiece. The hammers have two flat striking faces that are made of 4140 chromium-molybdenum steel heat-treated to 52 HRC and are jacketed with a hot cast polyurethane that's highly resistant to chipping, cracking, and tearing. The contoured handles and their textured surfaces provide a comfortable, nonslip grip for hammering, and the ends of the handles flare out prevent them from slipping out of your hand.,Tekton Dead Blow Hammers contain round steel shot inside the head to reduce post-strike rebound an
