Abstract
A gas-assisted scraping tool includes a housing having a blade support with a cavity that is connectable to a source of a pressurized gas; a blade attached to and extending forwardly of the blade support; and a diffuser attached to the blade support and spacing the blade from the cavity, the diffuser shaped to direct a stream of the pressurized gas from within the cavity lengthwise along the blade and distribute the pressurized gas transversely across a width of the blade, whereby material loosened by the blade is blown away from an end of the blade by the stream of the pressurized gas.
