Hate to own up to this but I spent Christmas Eve this year at the hospital removing fragments of dust out of my eye. I was using a circular saw and quick as a flash it spewed up dust and grit. I was wearing approved safety glasses but grit still managed to find itself in my eye. It hit with such force that the immediate reaction is to let go of the saw which I did for a brief second. I went to the doctor after numerous attempts at flushing out my eye failed, the doctor tried and got out most of the grit but said I would need to go to hospital where they completed the job. I don't know why saw manufacturers make saws that spew stuff right back at the operator but it is hazardous. By the way Alex'es theory about how this guy lost his finger correct? Also agree wholeheartedly with Wheelin, the two most dangerous tools are the bandsaw and circular saw, I have used every tool imaginable and these have given me the worst injuries.
