Can zoro use haki?

I say he will Be able to use Haki after there reunation but till now it's not stated he has used haki but i do tink he did use it to defeat mister 1 but it was never stated

Zoro will defenitly use haki. even for a -swordsman haki is neccesary.
he must be able to fight LOGIA types at least
or he will never reach his goal. So zoro will use HAKI

So we finally came down to the point where everyone agrees that zoro used haki in alabasta? That took some time.

yea most of us agree on it but it's not jet proven so we still not know if it was or wasen't
But Zoro will be able to use haki when he gets back atleast if he still wants to be the best he will eventualy need to learn it
