The Fiskars IsoCore Club Hammer has a forged, heat-treated steel head finished with a rust-resistant coating. Its extra-large diameter driving head improves strike accuracy. The wedged demolition face concentrates force for up to 5x more destructive power than traditional designs and directs debris to the sides, not back at you. SoftGrip handle with a sculpted profile to fit the natural shape of your hand. It also features a patent-pending strategic grip pattern with large dimples where fingers rest for maximum grip and small dimples where the palm rests to help prevent blisters. Whilst the handle flare keeps the tool firmly in hand when swinging. The Patented IsoCore Shock Control System absorbs strike shock and vibration to reduce the punishment your body takes, transferring 60% less shock and vibration than wood handles. Ref: UTTK4601
