> The blade guard helps too, but AFAIK, there are many instances where you can't use it.
Blade guards are rarely used in shops I've worked in. I've even worked in a shop that removed the riving knifes on their saws as they got in the way of certain cuts and they didn't want to spend time taking them on and off.
What sort of cuts would cause you to need to remove the riving knife?
Stumpy Nubs over on YT gave some testimony where he believes that a well-made blade guard could prevent most injuries. He believes that it's a culture around not using them (or poorly-made ones) that is the source of most injuries.
