ABSTRACT:
An impact handle for a shovel and other tools to assist the user or laborer in digging and/or moving material such as dirt or snow, or other compacted materials. An impact handle with a shovel attachment would have similar physical features as generic shovels on the market today. However, the impact handle includes an impact generator within the handle. As a user or operator applies his/her foot-pressure on the foot actuator located at the top of the scoop or blade, the impact generator using electro-magnetic principles produces impulses of 1 to 10 hertz of downward blows. These impulses reduce the effort required by the operator to force the tool scoop or blade to penetrate the material being excavated. The impact handle dramatically reduces time required to complete hand excavation projects. The impact handle can also be used, but is not limited to, to reduce the time required for chiseling, scraping, prying, nail pulling and carpet-stretching.
