摘要： A tool for scraping material from a bullnose installed on a corner joint of a drywall installation includes an elongated device having a handle portion, a first end portion, a second end portion, and a size adapted for holding in one hand. The first end portion has a first convexly shaped edge that matches a concavely shaped portion of the bullnose. It enables a user to scrape the material from the bullnose by moving the convexly shaped edge along the concavely shaped portion of the bullnose. Preferably, the first concavely shaped edge is shaped in a 75-degree arc of 0.875 inch radius to match a convexly shaped portion of the bullnose when the bullnose is installed on a 90-degree corner joint, and the second end portion of the elongated device includes a second convexly shaped edge that is shaped in a 50-degree arc of 1.125 inch radius to match the concavely shaped portion of the bullnose when the bullnose is installed on a 135-degree corner joint. One embodiment takes the form of a 6.5 inch long aluminum bar having the specified shaped.
