Abstract: A bone rasp device with a protective sheath and an extendable and retractable rasp for protection of the skin and soft tissue from the rasp during insertion and removal of the tool. The rasp device includes a tubular body having an interior surface defining a central opening extending between a first end and a second end with the first end defining a first aperture. A rasp portion, including a rough surface opposite a smooth surface, is connected to the tubular body and positioned within the central opening of the tubular body. The rasp portion is moveable relative to the tubular body. In a first position, the rough surface is contained within the central opening, and in a second position, with the rasp portion extends through the first aperture such that the rough surface is positioned outside the central opening and tubular body.
