Abstract
A tool for applying mastic (mud) to drywalls during the installation thereof. The tool has a quick opening feature for cleaning or manually filling a cavity with mastic. The tool is pivotally connected on the end of a handle with a controlled friction. A double-edged blade shapes the mastic as it is applied to the wall. The blade may be reversed when one edge becomes nicked or otherwise unusable.
