ABSTRACT:
A drywall edge shaping tool for cleaning and shaping bullnose corners is made out of aluminum flat stock. The tool has two shaping heads, one at each end, each shaping head having a concave shaping surface that is tilted at approximately forty-five degrees from the center line of the tool. The shaping edge of each shaping surface may be sized differently to accommodate different size bullnose corners. A putty knife cleaning groove is located behind each shaping head of the tool.
