31 oz. Dead Blow Ball Pein Hammer Canister filled with steel shot in the hammer's head creates a dead blow effect to reduce rebound . Dead blow design also sustains impact, maximizes force, and absorbs the shock of impact. Non-sparking, hot-cast polyurethane body covers the steel shot chamber and the steel reinforced handle. Steel face and pein excel at striking punches and chisels or shaping and straightening unhardened metals. Steel reinforced handle is strong and safe, built to resist breaking from an overstrike. Knurled texture on the handle with a flanged back end combine for a sure non-slip grip. Red polyurethane body is highly visible and durable enough for heavy-duty work . Made in the USA 68-540G
