From chapter 912. There's a naginata that looks like WB's in the panel too. Are spears swords?
Great search Cyrus
Meito aren't only swords, manga canon!
So WB is everything but a swordsman
"Among the countless weapons"
Countless weapons=swords, spears, etc. (that "etc." Can be literally everything, naginata, kukri, even small pocket knives)
Actually there were many misconceptions about swords and swordsmen in One Piece community, all of them are slowly being proven wrong:
-WSS is only about skills
-Swordsmanship doesn't include haki
-Wb has a Meito so he is a swordsman and since that Wb is stronger than Mihawk then also Shanks could be
Man, people yet don't realize, but that Oden guy is a literally hype fuel for those the fandom called "pure swordsmen" like Mihawk (btw, that category doesn't exist in manga, it's only anti-swordsman fan's propaganda only).
But let's assume that such a distinction actually exists.
Oden proved you that also a "pure swordsman" can be as strong as hell.
Oden clashed with WB, is the only one to have scarred Kaido etc.
I swear, I remember a user tried to push that Oden isn't a pure swordsman propaganda in order to downplay Mihawk, he was blatantly proven wrong in just few chapters.
Once he was proven wrong he rapidly switched from "Oden isn't a pure swordsman" to "Oden's feat doesn't transfer automatically to Mihawk".
I mean, why?
Oden is just a stepping stone to Zoro, it's implied in Wano, while Mihawk is the ultimate goal.
I want to leave a small suggestion to end this message: when it comes to Zoro don't try to interpret everything related to him in a restrictive way.
That ain't what Oda wants (Don't speak ill of Zoro).
