A hand operated tool for cutting and trimming mounted wall covering materials including paper, cloth, canvas, vinyl plastic, cork and the like. A large wiper blade for smoothing out the covering materials is provided with at least two marginal guide means which cooperate with an adjacent wall in guiding the tool for linear movement along the intersection of two walls. A knife blade is mounted in a holder fastened to the wiper blade in position to project beyond one corner of the wiper blade and guide means in accordance with the desired depth of cut, as dictated by the thickness of the covering material, and to dispose the cutting edge thereof at a proper angle for smoothly severing the covering material.
