## Narrative

Miner was using a pedestal grinder to sharpen the edge on a steel wedge.  The miner raised the wedge too high and the grinding wheel grabbed it and forced it into the tool rest gap of the machine.  The minor's thumb got crushed between the steel wedge and the grinding wheel which resulted in an amputated left thumb tip requiring emergency room surgery.
