I came across this video about a YouTube creator’s table saw injury. It’s NOT graphic (although if that’s your bag there a link in the video description to his blog post with more detail). I’ve noticed a couple of times lately that someone has removed the guard for the table saw (totally fine if it’s needed for a cut), but hasn’t installed the riving knife in its place (not OK, either the guard or the knife should be installed). This video describes exactly the type of situation that a riving knife is designed to prevent.
Our SawStop is a very safe machine, but it can’t prevent kickbacks, so paying attention and safely operating the machine is still suuuper important (plus it keeps us from having to replace the brake and blade).
