ABSTRACT:
A wall corner finishing tool includes a pair of plastic blades connected by a living hinge. The proximal ends of a pair of arcuate arms are hingeably connected to the back sides of the blades. The arms are curved toward each other so as to overlap at their intersection. The arms include longitudinal openings extending therethrough. A handle is attached to the intersection of the arms by a screw extended through the openings and into one end of the handle. When the screw is loosened, the arms can be moved toward or away from each other to adjust the angle between the blades. When the blades are positioned at a desired angle, the screw can be tightened to fix them in position. The blades can be adjusted for finishing wall corners of a great variety of angles.
