Everything you wanted to know about saw blades.

First, please don't accuse me of being a shill. I was looking for information and sources when I came across this chart.

I suspect that the usefulness ratings on the right side of the chart apply generically across most saw blades.
(Some saw blades are only good for finding nails but we won't get into that here.)

The left side of the chart sort of explains tooth configurations and hook angle.

Actually, I wish that I had this chart years ago. There is so much good general information about saw blades that I can see the stupidity of my blade purchases for my long gone RAS.
