I'm not so certain it's stupidity that causes problems. People who get injured on saws aren't first-timers doing dumb things. They're thirty-years-in-the-business people who either lose respect for the tool because nothing bad has happened in thirty years, or they just get distracted for half a second. That half a second is all it takes. Salesman at my local tool store is missing three, and he lost them just last year, thirty years in. The workpiece was falling off the outfeed side and he reached over to catch it and that was all it took.
I didn't buy the SawStop for the brake so much. I bought it because it was the best saw for me. It was the exact right height, it felt right, it had the accessories I wanted, it had a riving knife, it had wheels so I could move it out of the way, it fit into my space, it had that huge table, it was so smooth and sawed like a dream and was really quiet for a saw. I fell in love at first touch. The fact that it was also the safest saw on the planet was the icing on the cake. Make no mistake, though, I bought the cake. If the icing weren't there, I would have bought plain cake anyway. All these years later, the icing is pretty darned cool in itself. I worry a lot less when the teenaged grandsons come into the shop. If the brake is ever tripped, I'll be really bummed because that will toast both the brake and my Forrest Woodworker II to the tune of a couple of hundred bucks. A pittance compared to $20K per digit to have them sewn back on afterwards. I hope I threw away $1000 buying the SawStop. $50 a year of insurance for twenty years of work. I can live with that quite nicely.
