i just bought an ND yoyo and i found that the string keeps breaking, i took it apart and found that the bearing seat is real sharp i tried fixing it with scotch brite pads but i found that that just made it sharper. does anyone have any other recommendations on fixing it?

A lot of people here say that rubbing should be done with denim and that works well.
