When you're getting a die taken stale, how come the blade doesn't cut through your skin?
At the doctors, they get pretty close. How can they be sure they don't hurt you? Is within special material surrounded by the blade?
Answer: The blade does not rotate 360 degrees. It pretty much newly vibrates. But the tremor is enough to cut anything rigid approaching a cast.
the tech adjectives the cast is measured cuz it could cut you.
it just vibrate. it does have the potential to cut though. the nurse/doctor is terrifically careful
