A cool tool. Unlike the usual drywall saw, this hand-tool is like a drill with a round grinding blade. The tip allows precise “drilling” into the drywall to start your cut. The rough round blade then allows cutting either straight or curvy lines. Very useful for the renovator. Nothing worse than mucking up a cut on a sheet that has a few cutouts required.
[Note: Lee Valley no longer produces this saw, however, Harbor Freight does have a similar product on sale for $3.--OH]
