Steel shot inside the head of this specially-designed 32 oz. dead blow hammer eliminates post-strike rebound common with steel and other solid-head hammers. Controlling this rebound conserves the energy of each blow, redirecting it completely into the work piece. This means fewer blows are needed, reducing the chances of deforming the work piece. At the same time, work surfaces are protected by the high-impact poly jacket that completely encases the all-steel head and handle. This jacket gives a positive strike while preventing marring of softer metals like aluminum. The handle is finished with a comfortable diamond tread pattern for a non-slip grip.
