When I broke my leg I was given a plaster cast. After a couple of months this was removed at the hospital using a rotatory saw. This sliced through the cast with ease, but I noticed that when it touched my skin, it didn’t hurt at all. How is this possible?

Chances are that it was actually an oscillating saw even if it had a round blade. Those just swing back and forth a little bit. That makes them good at cutting hard things and bad at cutting soft things.
