Peptides synthesized to match N-telopeptide components of type III collagen degradation products in body fluids, selected from among DVKSGVAVGG, YDVKSGVAVGG, SYDVKSGVAVGG, DSYDVKSGVAVGG, JYDSYDVKSGVAVGG, and KSGVAVGG are claimed. The device comprises at least one fixation pin for fixation to the head, a sleeve member having an internal threaded through bore to at least partly receive and hold said fixation pin, and a pin support member for supporting said fixation pin and sleeve member. The body has a first flute providing a first flute cutting edge at a distal end of the body for imparting a first cutting operation to the workpiece. With this structure, during rotation of the agitator, greater stress may be produced in the outer end of each end area than in an inner end of each end area and a center area in its entirety. If a match occurs, a contact notification is generated.
