I say it could just be visual similarity.
My counter argument is other stuff in verse which wouldn't make sense if Greenbull was strong enough to forge a black blade:
- zero indication that his main fighting style is swordsmanship, didn't use it even once and instead fought fully with his DF (flip GB by Fujitora, and at least I can see arguments that he could have a black blade, whose swordsmanship is even integrated to his DF usage)
- scabbards didn't comment on it
- shocked by Shanks' haki and got reduced to base. You think this would happen to someone with strong enough haki to forge a black blade? Mihawk would have this reaction, when he snubs Shanks to his face?
- him not negging Morley in base instead of complaining about constraints
And again, my problem isn't anyone theorizing that it's a black blade.
People come up with tons of theories. My problem is dudes treating it as a fact, and sperging out against anyone who disagrees with them.
Oh, then just wait for it to happen?
And no, it isn't a fact until it's mentioned in manga.

But evidence says otherwise
Let me ask you another question
Have you seen a sword (other than yoru and shisui) being not used but still being drawn as black across VC, volume and in manga?
