Yeah. If somebody tried to cut a cast off my hand with 10” circular saw I wouldn’t jump. I’d calmly pick up my chain saw and fight back.
My sister cut one off too early with tin snips, it itched so bad. The doctor had a fit but had to put an inflated air cast on her ankle. That worked. And when it came time to take it off, there came into the room the sibilant hiss one hears when a tire runs over a nail. Casts can itch something fierce.
