User blog comment:Juraquille Mihawk/Hawk-Eye Haki/@comment-3060121-20110309175527

I believe that Mihawk does have haki but with no evidence, there is really no way to defend it. Mihawk not cutting buggy was because he was battling a rubber man, someone whose weak to swords. In addition to that Mihawk probably knows that buggy and shanks are connected.Rayleigh says that haki is dormant in all creatures so Mihawk has it because everyone does. I believe that Mihawk also knows how to use it but hasn't. No one has been able to challenge him yet beside Jozu,who we know has haki. So he hasnt used it.
