Especially when you recoil in pain as it unexpectedly scrapes your finger; it's likely you'll just release your grip entirely, so it'll fly off in a random direction, slicing through anything it hits, possibly bouncing and/or breaking the disk, before it runs out of kinetic energy. $deity help you if the trigger lock is on.
