It limits damage in a massive, massive way for a whole lot of accidents. It doesn't just slightly lower the amount of injury you'll get. Look at the high speed videos out there. Sharp blades at high RPM will do damage... but the blade stops in something like 3 teeth moving past your finger. If you slap it like you're playing whack-a-mole you might get a lot of damage cut, but you're really over-minimizing how much of an effect the blade stopper can have for, say, a kickback causing your hand to pull into the blade. It turns a "cut your finger off" accident into a "get some stitches and Tylenol" accident. Studies have shown this to be true:
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4154236/ There are more than 30,000 table saw accidents annually. Most of them are finger or thumb injuries, which are likely to be caused by blade contact (as opposed to a kickback, which Sawstops don't help with). The mean age of an occupational injury was 40 years. Assuming someone's been working in that career since they were in their 20's, that means the average table saw injury happened to someone with 15-20 years of experience.
Regarding "slamming" someone- your first post erroneously says that the SS won't prevent much damage in a tone that clearly implies that anyone who thinks otherwise simply isn't thinking about it enough. "Do not let fear control your life"- clearly, in the context of your post, you're saying anyone who buys a Sawstop is just letting marketing speak and fear control their lives. In your next post you say "You can get a real saw", which is clearly again an insult to anyone who likes their Sawstop. If someone said about your car "Well, if you get a
real car, then..." or "Well, if you were a
real parent, you'd..." That's what I call slamming. You might not be meaning it that way (since of course you can't convey much emotion through text) but that's what the words say. Consider how you'd feel if someone said that about you. Would you feel insulted?
No, I'm not sponsored by Sawstop or anything. The only one I've used is at my local Woodcraft for classes and it seems to work fine and is a well made saw. I use a slider at home.
Not to mention a Hammer K3 Winner, while definitely a great saw, is $5700 minimum, whereas a Sawstop is about 4k. A 40% higher cost isn't anything to sneeze at.
Last- I fully agree you should have complete focus 100% of the time you're operating a tool. A Sawstop is not a reason to be sloppy. It's a "belt and suspenders" system that helps if you have a momentary lapse of judgement or if something kicks a weird way. In that regard it's similar to a blade guard. If you were 100% focused at all times you don't need a blade guard... but we're not robots here, we're people, and sometimes we make mistakes.
