A flat surgical cutting instrument, usually made of high-grade stainless steel, with a serrated edge designed for attachment to a dedicated powered saw used for cutting bone/tissue during orthopaedic or oral surgery; it is not dedicated to cutting through the sternum (i.e., not a sternum saw blade). This device is designed with the cutting teeth arranged in an arc or on a flat plane pointing directly forward at the distal end to cut in a rapid sagittal (side to side) motion; it may in addition cut in an oscillating motion. This is a single-use device.
