User blog comment:Red HAired Shanks/Does "Hawk Eyes" Mihawk possess haki???/@comment-2109035-20101111025544

Not all strong people have haki, Blackbeard and his crew don't have haki, Crocodile doesn't have haki, Daz doesn't have haki, etc. Really, only the Yonkou, some of the Shichibukai, and few pirates underneath the Yonkou have haki. I think that Mihawk, really, feels he doesn't need to use haki, as his main opponents would be other swordsmen, and he might feel it cheating if he used haki to predict the other's movements.
