Abstract:
A blade including a body has a front surface and a curved back cutting surface. The front surface has a mount angle relative to a material surface of a material feeing the back cutting surface. The back cutting surface has a substrate clearance angle relative to the material surface. In response to at least one of the blade and the material surface being brought into cutting contact and moved relative to each other, a resulting portion of the material surface has a distressed appearance.
