摘要: A tool for simultaneously finish edging the wet cement surfaces abuting both sides of divider strips which separate the wet slabs is disclosed. The tool has a pair of blades adjustable to accommodate a variety of divider thicknesses. One of the adjustable blades is spring loaded and floats so as to compensate for changes in the width of the divider as the tool moves along its length. A blade may be removed if only one edge is to be finished.
