I did. Mihawk is stronger than any swordsman. Kaido doesn't become a swordsman just by picking up a sword in the middle of the fight, he becomes one by using a sword regularly and consistently. If Kaido picking up a sword in the middle of a fight makes him a swordsman, do you consider Luffy a swordsman for when he waved those two swords around when he fought Arlong? If your answer is yes, you're an idiot. If your answer is no, then your argument falls apart. Your choice.
picking up a sword does not make him a swordsman and neither does using one frequently the way shanks does
shanks has incredible haki so he uses a sword frequently but doesn't rely on swordmanship abilities he relies on haki, he is not a swordsman just a haki beast that uses a sword
