ABSTRACT:
A tool for scribing lines in soft concrete in which the line can be impressed by a standing operator. Guides are provided on the tool to assure a proper angle of the scribed line. A grooving tool can then follow the scribed line without added guide because the line will be located and all rough aggregate in the concrete will have been moved out of the path of the grooving tool.
