Fiskars 8 lb. 36" Handle Sledge Hammer is a powerful tool that is perfect for demolition projects. The hammer features an Isocore Shock Relief System that helps to reduce vibration and shock, making it more comfortable to use. The wedged demolition head concentrates force for maximum destruction and directs debris to the sides, not back at you. The extra large diameter driving head improves strike accuracy, and the 36" ergonomically contoured handle fits the natural shape of your hand. The bio dynamically engineered texture offers a secure grip, draws moisture away from your palm and helps prevent blisters. The hooked handle keeps the tool in hand when swinging with maximum force. The hammer is forged and heat treated steel and finished with a rust resistant coating. It is tested to exceed ISO 15601 standards for striking tool durability and comes with a full lifetime warranty.
