True, you can be a very skilled swordsman while being a subpar haki user.
Oh? So then What is the measure of your skill?
as in what exactly proves you’re a “very skilled swordsman”?
As far as I can tell, the only measure of sword skill in the Op verse is winning fights, the “more skilled” swordsman is the one that won the fight… What is your measure
Who told you that Vista didn't have a Sword Style?..
Kinemon's Epithet is Foxfire Kinemon, even though he has a Sword Style, Foxfire Style..
Humming Brook - Humming Sword Style
Flower Sword Vista - Flower Sword Style
Foxfire Kinemon - Foxfire Sword Style
Pirate hunter Zoro - 3 sword style, Nine sword style, 1 sword style, 2 sword style and KoH 3 serpent dragon (Zoro has 5 sword styles and no Pirate hunter style, he also has a Bar handed fighting style called “No sword styles”)
lingering Snow Kikunojo - No sword style stated anywhere.
ship cutter T-bone - Right angle Fencing style
Napping Koushiro/Denjiro - Oden two sword style
Hmm, so we have a mixture of People’s epithets having nothing to do with their sword styles and people’s epithets having nothing to do with the sword style they have or they straight up have no sword style at all
So… Why are assuming Brook and Vista follow Kin’emon and have a sword style based on their epithets?
Vista has 2 swords style, different than Mihawk's style.
Shiryu has super fast battojutsu style which is now amplified with his invisibility attacks, also different than Mihawk's.
And shanks has a 1 sword style, different than Mihawk’s style
