When he looked down, he saw his finger lying on the bench.

At the risk of starting another Saw Stop vs push stick thread - The biggest take off this statement that I get and know is that a serious injury doesn't immediately hurt as much as it will do in the next few 5 mins/hours/days and months/ maybe years - It's amazing how the body reacts at the time.
That is no consolation though when it happens. Safe cutting to all.
