Relax guys, do not fall for the provocations of the fans of the pedophile and the human condom. Luffy used haki, G5 (his most powerful state) and techniques to not KO Lucci, since after a few minutes he was as good as new xd. Zoro simply blocked Kaku's attack, and sent him flying with a technique, just like in the Pretimeskip when they collided and Zoro sent him flying with the Ichi gorilla Ni gorilla, it's not a damage attack, it was a pulse and Zoro defeated easily, that's why he didn't make a cut.
