Fiskars 10 lb. 36" Handle Sledge Hammer is a powerful tool that is perfect for demolition projects. The hammer features an Isocore shock relief system that interrupts the path of vibration from the strike, reducing the shock and punishment to your body. 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. The 36" ergonomically contoured handle fits the natural shape of your hand and the bio dynamically engineered texture offers a secure grip and draws moisture away from your palm to help 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. The hammer comes with a full lifetime warranty.
