I looked for it everywhere, i just can't find the metal fury version. Can you guys help me?

As my Blitz got broken, just searched eBay myself too.

Seems there is no other way than getting Sono Kong BB117 set.

All those I've listed are written to be originals.

That's right, even if way lighter Hasbro's one is made in a single piece. So it doesn't suffer about breaking problems, plus i could use it in the ltd format...

I've intentionally skipped Hasbro hollow version as being much weaker. But limited format gives it another use which I did not think about because we did not have any metal tournament since 2013.
