A hand-held tool. The tool comprises an interchangeable blade or blades located at an end of an L-shaped frame. The frame has a first portion and a second portion, the first portion attached at its end to the second portion in perpendicular fashion. The blade is located at an end of the second portion and has a working edge, which may be sharp, rough, serrated, or otherwise adapted for an application. A motor supported inside the frame provides reciprocal motion to the blade, the motion in a direction parallel to a length of the first portion of the L-shaped frame.
