As featured recently on Toolmonger, the SawStop table saw features a safety system that starts by inducing an electrical signal onto the blade. If your fingers (or any other part of your body) come in contact with the blade, the signal changes and the blade retracts within milliseconds, leaving your fingers with only a scratch. SawStop currently offers only one product, the table saw, but they’re working on some other stuff. These two quick videos give a first look at future SawStop products.
Note to viewers: imagine that the hot dog is your favorite finger.
