Zippos only if they’re empty. Who had empty zippos without lighter fluid?

The phrasing on the TSA website suggests that lighters with fluid are permitted in your carry on, just not your checked. This is also in line with the policy in Canada.
Whether the particular TSA agent you’re stuck dealing with actually knows their guidelines, well… don’t hold your breath, they also get pissy about frozen water bottles (which also are allowed).
