...So yes - assume high-power tools are out to maim and kill you so stay on highest alert when using them.

Your statement is absolutely true, but the picture of the saw blade & fingers is not. It should be red all the way around. I have what started out as an eigth-inch notch in the tip of my left middle finger. These days you can barely see a slight depression in the end of the finger. I calculated the approximate number of hits on my finger based on the 80-tooth blade and the rpm of the saw. I figure I got hit at least 4000 times in the maybe a tenth of a second it took to cut that notch.

I notched the tip of my thumb about the same way. Was about to install the last piece of laminate flooring and had to trim the edge a bit. Made the cut and in my haste to grab the remnant I forgot the blade was still turning and it sliced into my thumb a quarter inch. All healed up now one side of the thumb tip is still numb after all these years.

I was trying to use an illustration less upsetting than actual photos of the subject. Just think of that red all around the blade like the curing of a cast iron skillet...and proof you put a little bit of yourself into your work.
