ABSTRACT:
This is a tool for troweling masonry steps so as to provide a slight slope on the top of the step. A post is pivoted to the trowel blade near its front end, and it supports a roller for overlying engagement with the top of the riser form at the front of the next higher step. The roller is adjustable along the post to a height suitable for holding the front end of the trowel slightly elevated.
