> Circular saws, mitre saws are sold with protective elements where I live. To respect, but it won't jump out and hurt you.
That's true but they're not sufficient to protect against all injuries if you don't take proper precautions. And, as far as circular saws go, you're flat out wrong about them not jumping and hurting you: if they bind up in the wood that's exactly what can happen in the worst case. It's called kickback.
SmarterEveryDay prototyped an anti-kickback mechanism for circular saws[1] that I hoped would inspire some mfgs; it's crazy that we haven't seen more safety innovation in handheld power tools 10+ years after SawStop became widely viable.
