I've been thinking to myself about what the safest and most dangerous tools are in the shop. Someone told me bandsaw was the most dangerous once, but I think that may be the safest saw in the shop. It's hard to determine the safest because all power tools are dangerous, but I think the most dangerous is the table saw, eapecially without sawstop. There's so much that could go wrong. Obviously, it's relatively easy to cut your finger off, and in many ways. You also have the risk of kickback which creates safety issues. The is also a high risk of long clothing or hair getting caught in the blade.
As for safest, talking power tools only, I think planer is because no blade is actually exposed. If you stick your hand in the machine, you are in for a bad day, but that's not something done by accident
