I bought this diamond shaping tool and used it to create my own rounded edge on granite countertops. expensive, but still better than paying a few hundred dollars to a granite specialist. First cut a strip of granite about 1.5 inches wide, "glue" this strip to the underside of the countertop with granite epoxy, clamp and allow to dry - Sand the edge into a bulbous nose shape with one at a time Angle Mounted Adjustable Speed Hand Profile Grinder - Finish the end result with diamond polishing pads for a brilliant finish. The profiling tools even give a nice rounded edge on the corner of the countertop, let it slide around the corner around the edge.
