ABSTRACT:
A hand tool for forming the interior edge of a cementious surface. The tool which consists of a flat inflexible rectangular plate shaped such that shorter leading and trailing edge curve upward, and one of the longer edges has a central portion curving outward and downward, and with the length of the right and left non-curving portion of the edge being the same as the leading and trailing edges. With this configuration, the mason slides the tool along the edge of the cement surface and reaches an intersecting interior corner, the tool is lifted and run along the adjacent edge until corner is reached. The tool permits a mason less skilled in the mason art to execute the interior corners of a cementious surface without surface blemishes or groove marks.
