## Narrative

After removing the retaining screw, the lock ring on the fines screw was still stuck.  The employee used a chipping hammer and a 4lb sledge hammer to tap it loose.  When the employee struck the chipping hammer with the sledge hammer, a piece of metal broke off the tip of the chipping hammer, went through his leather glove and into his left thumb.
