Abstract
An adjustable drywall corner tool comprising a pair of work engaging blades normally disposed substantially at a ninety degree angle to one another. A hinge extends between mating edges of the blades. A structure is for changing the angle between the two blades, so that the blades will fit in an inside corner of more and less than the ninety degree angle. A handle extends from the angle changing structure, so that a person can grip the handle to apply taping to the corner.
