An adjustable handtool is provided for finishing corners, edges and the like with cementious material to effect a uniformly rounded configuration to the corner. The hand tool includes a backing plate having a forward working edge characterized by an indented central portion and forwardly extending legs forming a first obtuse angle. Overlaying the backing plate is a pliable sheet which also has a forward working edge characterized by an indented central portion and forwardly extending legs forming a second obtuse angle which is larger than the first obtuse angle such that the working edge of the pliable sheet extends beyond the working edge of the backing plate. The backing plate is preferably manually bendable to suit an individual craftsman and to obtain a working region which has cooperating curvatures at the working edge of the backing plate, at the working edge of the pliable sheet and as caused by the bend.
