A photo of the 'freewheel' would help and we can confirm if its a freewheel or freehub with cassette. Picture from the side please.
I don't think I ever used a chain whip in freewheel days, and the broken tool looks like a freehub remover.
The damage suggests it has slipped off the cassette lockring - a good tip is to stick the skewer back in the wheel after inserting the remover, then tighten down the skewer nut to hold the tool in place.
