Abstract: The present invention is directed to a tool for troweling masonry steps which employs a convenient arrangement for swiftly positioning the trowel blade with a slight and easily repeatable consistent slope. To ensure uniformity, the present invention has an adjustable member which rides along the form of the step immediately above the one being trowled allowing an easily reproducible slope. In a preferred embodiment, a calibrated bubble level is included in the handle of the trowel which permits the stair finisher an indication of the angle of the slope he is producing.
