as to bent up and messed up attachments - since I collect them, I've seen a lot! I think they got played with, taken apart, reattached incorrectly - used as screwdrivers or pry tools- and who knows what else.
It's funny when someone has a set with the attachments taken apart, and they brag about having a "rare" set with 10 pieces when the "normal" sets only come with 6.
I probably have about 20 lbs of "messed up" attachments -
