Abstract
In its preferred form the present invention provides a tool for scarifying wallpaper, to create holes by which steam or water can get behind paper stuck to a wall and thereby assist in removing it. The tool includes a pair of sharp toothed wheels rotatably mounted at an angle to each other on a rolling or pivoting block, so that rolling or pivoting the block between two positions can alter the angle between the two wheels in relation to the wallpaper, to be appropriate for scarifying movement of the tool either backwards or forwards.
