Abstract
The present invention includes a specialized tool for finishing drywall surfaces in areas where there is a joinder of those surfaces at an included angle greater than 90.degree.. The tool has an arcuate blade having a handle protruding from its diametral edge, and with a spine extending longitudinal outward from the handle along a radius of the arcuate blade to a point in proximity to the edge of the blade. The blade is of uniform thickness and terminates in a finishing edge which is tapered to a thinner leading edge. Further, the tool has tapered raised portions fanning out from the spine to enhance control and stability of the finishing edge.
