Abstract: A hand-held wallpaper trimming tool symmetrically adapted for either left-handed or right-handed use which facilitates accurate and precise cutting of wallpaper along a joint between a wall being papered and an adjacent structural member. A guide portion is provided with a body member having a conically-shaped portion for resting against the adjacent structural member and gradually feeding the wallpaper into the joint, and with a pair of flat flanges for left-handed or right-handed use of the trimmer, alternatively, each attached at one edge thereof tangentially to the conical portion of the body member for placement against a wall being papered and pressing the paper smoothly against that wall. A selectably extensible cutting blade disposed at the apex end of the body member is mounted in a blade holder and secured by a releasable fastener. The blade holder may be rotated for orientation of the blade at a plurality of angles to the flanges with its cutting edge facing toward one or both of the flanges.

Abstract: A hand-held wallpaper trimming tool which facilitates accurate and precise cutting of wallpaper along a joint between a wall being papered and an adjacent structural member. A guide portion is provided with a conical body member for resting against the adjacent structural member and gradually feeding the wallpaper into the joint, and with a flat flange attached at one edge tangentially to the body member for placement against the wall being papered and pressing the paper smoothly against that wall. A selectably extensible cutting blade, such as a single-edge injector razor blade, is mounted in a receptacle at the apex end of the body member and secured by a releasable fastener. The blade is oriented at an angle to the flange with its cutting edge facing in the direction of the plane of the flange. An elongate handle, projecting away from the body member and away from the flange is mounted at the base end of the body member for manipulating the device.
