Can't believe it actually happened to me, thought I was immune. I'm ripping some boards on the tablesaw for my daughter, very late in the day, I'm very tired. on the last cut, and somehow I nicked my thumb on the sawblade as it is running down. Luckily it is not a serious cut,just a deep scratch on my thumb.
I'm not a newcomer to the tablesaw, having owned one since 1960. I guess it can happen to anyone....take heed!
