An impact tool is provided for applying impact energy to a material, the impact tool comprising a fork portion having a first tine, a second tine, and a base portion; an exciter component at one end of the first tine, configured to excite the first tine to resonate at a given frequency, the second tine configured to resonate sympathetically with the first tine; and a striking surface on one or both tines, the striking surface configured to contact the material so as to apply impact energy to the material. A method for applying impact energy to a material is provided, the method comprising raising the tines away from the material; actuating the exciter component to cause the tines to resonate at a given frequency; and positioning one of tines to strike the material so as to apply impact energy to the material.
