An impact handle 10 for hand tools to assist the user in digging and/or movi ng material such as dirt or snow, or other compacted materials. An impact handl e 10 with a shovel blade 41 would have similar physical features as generic shovels on the market today. However, the impact handle 10 includes an impac t generator 20 within the handle. As a user or operator applies his/her foot- pressure on the foot actuator 25 located at the top of the blade, the impact generator 20 using electro-magnetic principles produce oscillations of 1 to 10 hertz to an impact slug 28. These oscillations reduce the effort required by the operator to force the tool scoop or blade to penetrate the material bein g excavated. The impact handle 10 dramatically reduces time to complete hand excavation projects. The impact handle 10 also reduces the time required for chiseling, augering, scraping, prying and carpet-stretching.
