Speculations Is S-Hawk's Yoru replica supreme blade level?

[Shiroyru]

If Vegapunk can perfectly replicate DFs, than I don't see why he wouldn't be able to replicate a supreme grade blade

Vegapunk's a blacksmith too?
If the blade isn't made of seastone to counter logia users then we can forget about Vegapunk being a genius.

I believe no sword born ranked. The rank is given to the sword feats.
