## Narrative

A mechanic was attempting to move a retainer bolt from a hardnose pivot pin. The socket slipped off the bolt head and his face came in contact with the stabilizer bar. This caused a laceration to his chin and a chipped/cracked tooth. The laceration required four sutures and the tooth required crowning procedures.
