I've had at least 4 fake blades, and all of them broke after a few matches, with Black Dranzer breaking a few, I cannot see how it's a fake and last that long. It's not fake, period.
EDIT: I would differ on the molds, if you look closely at Dranzer F you can see the white marks at the ends of the claws, only after a few battles, and it's a Hasbro model. Whilst Black Dranzer, you cannot see anything and I've been using that for ages. It's common knowledge that Takara models are far superior than Hasbro in terms of molds and types of plastic used.
