Abstract: A step groover apparatus has a housing to which a direct drive means is attached. The drive means has a rotatable shaft extending into the interior of the housing and on which a plurality of grooving blades are fixed in space relationship. The blades extend through an opening in a lower portion of the housing. The housing has front and rear skids on which the apparatus slides as it moves along the top of the step. The skids are vertically adjustable to vary the depth of the groove to be cut in the step. A vertically and horizontally adjustable face guide is adapted to be forced against the face of the step so that the grooves will be parallel to the step face. A radially extending handle is attached to the housing so that the rear skid may be pressed downward against the top of the step. A laterally extending handle is attached to the housing so that the front skid and the face guide may be simultaneously pressed against the top and face of the step, respectively.
