DeWalt aims to reduce muscle fatigue with the introduction of its DWHT75900 Carbon Fiber Composite Hammer Tacker. Prolonged exposure to vibrations on the jobsite can cause discomfort, and traditional tackers are often made of die-cast aluminum, which is bulky, heavy, and tiring to use. DeWalt’s carbon fiber composite material weighs 45% less than other industry-leading hammer tackers and reduces vibration levels by 45% and muscle effort by 25%, allowing users to work longer. It drives 5/16-, 3/8-, and 1/2-inch heavy-duty staples. Online price is about $40. dewalt.com
