Mihawk is arguably one of the strongest characters in the series. His swordsmanship is said to be the greatest in the OP world.
However being the strongest swordsman doesn't mean, that he's able to hurt Logia type devil fruit users, and therefor is weaker then any of them. But lately, every strong character during the Marine Ford arc. has been seen using either one of the only two ways of countering Logias without having to use their elements natural weakness : Seastone weapons (Vista/ Benn perhaps) or Haki (Marco, Jozu, Dolflamingo and others).
SO I CAME ACROSS AN INTERESTING FACT :
If you attack a DF user with Seastone, or using Haki, then the DF's power should be canceled where the hit was placed (like Garp punching Luffy, bypassing his rubber body or Smoker damaging Luffy with his Jutte).
However, Mihawk attacked Buggy's split body, and Jozu's Diamond body (albeit at a range), but wasn't able to hurt them at all. The given explanation, would be : "that they're immune to bladed weapons".
From www.onepiece.wikia.com : While Juracule Mihawk is indeed extremely powerful, because of the versatility of Devil Fruit powers, there are those who cannot be damaged at all by his attacks, such as Diamond Jozu and Buggy.
BUT IF : Mihawk is a Haki user, or his Sword is made of Seastone, shouldn't he then be able to hurt them, like if he hurt a Logia with Haki? (Like Silvers Rayleigh hurting Kizaru, or Shanks blocking Akainu's attack on Coby).
IS MIHAWK EVEN CAPABLE OF HURTING LOGIAS? Is the world's strongest swordsman, SHIT compared to an Admiral or any other Logia?
Take a look at this picture :

Yes, here we see Mihawk clashing with Crocodile. His sword, hits Crocodile's HOOK, which is made of Gold in his natural form, but can be turned into sand. Crocodile isn't showing any signs of using his DF ability on the picture, but if he was, then IT would prove, that Mihawk can damage Logias in some way.
I just posted this, because this might be a giant future plothole in my opinion, and if I'm right. So enlighten me, or simply debate this tread!
