Routers for me as far as ruining the work goes, circular saws for losing digits. I have managed twice now to cut through my circular saw cable while doing various jobs around the house, thank god for safety switches. At least now the cable is short enough it doesn't get in the way 👍
They're all ganging up on you! At least you now know and can do something about it.
