While there is no doubt that S-Hawk’s sword is nothing like the real Yoru, I think it’s very possible that it could be a supreme grade and that there are now 13 supreme grade swords due to this invention by Vegapunk.
S-Hawk fought two haki users, Zoro and Kaku, yet despite this the sword is still intact. Therefore this cannot be a normal sword.
We know how easily Zoro can destroy normal swords. The sword of S-Hawk’s must be greater.
Given Vegapunk’s immense knowledge, imo it is very likely that he could have devised a method of creating supreme grade swords, just as how he can clone mythical zoan DFs.
