+User - the user may receive cuts from tools while handling or sharpening them. They may also be cut by sharp edges on the workpiece. Long swarf can wrap around the workpiece causing unexpected sharp edges.
 
 ### Control measures
 - Training - user should not touch cutting surfaces at any time, and should be aware of potential sharp edges on the workpiece. Workpieces should be sanded where appropriate before being considered "finished."
