Abstract
A blade for cutting a groove in ductboard and forming a corresponding scrap strip of ductboard. The blade includes two blade portions depending from a support member such as a hand tool with a sled for engaging the ductboard. Each of the blade portions includes an inner end which engages the other inner end to partially fix the blades relative to each other and partially restrict the blades from spreading which may be caused by the horizontal grain of ductboard.
