Abstract:

A trimming tool for trimming the edges of wallpaper in which separate razor blades are supported on respective arms slidably mounted on a handle for movement between extended operative positions beyond the edge of a blade member secured to the handle. The arms are urged by springs to the retracted position in which the razor blades do not project beyond the edge of the blade member. Manually engageable projections are provided for the individual displacement of each arm to its extended position against the opposition of the springs, the arms being individually displaceable, one at a time, to bring the cutting edge of the associated razor blade beyond the edge of the blade member into its operative cutting position. When the tool is moved in one direction, the razor blade at one of the side regions of the blade member is extended to cut the wallpaper along a line of cut while the edge of the blade member guides the tool and when the tool is halted, the razor blade at the other of the end regions of the blade member is extended and the tool is moved in the reverse direction to complete the line of cut.
