Duncan yoyo Metropolis

The metropolis has a slight flaw that could effect play.
Along the response ring is open tethered metal which in turn, cuts the string during play.
I could still use the yoyo but dropping it is one of the worst thing to do to a yoyo.

yea so many people have noticed this. theres not much you can do except maybe tak some sand paper or a grinder to it and get rid of the ring.
