For over 20 years now, professional woodworkers have had SawStops, devices that literally use an explosive charge to ram a block of aluminum into the blade of a table saw when it detects that the blade is touching something that might be a human body part. These are $50+ devices that destroy themselves on use (and often destroy the $50+ blade they’re used on), they have a high false positive rate, and yet they’re still in heavy use and very popular with professional woodworkers. Table saws also have riving knives and sleds with clamps, both to prevent kickback. All of this on top of constantly educating woodworkers to be responsible and use push blocks instead of their hands, to boot. All of these safety features exist on table saws because we did educate woodworkers on how to be responsible, and we still saw that the average table saw will cause more than one injury in its lifetime. I’m actually really glad you brought up woodworking because table saws are a perfect example of how we saw “this is risky, be responsible” was inadequate.
