"Club" is a broad term.
I would say this for once. You could probably use a hanbo, but only get the club-stats for it.
Hanbo is a specific kind of staff used in eastern martial arts. If you look at these pictures here or just google "hanbo", you'll notice that while the description given for the hanbo kinda fits Ezren's stick, it doesn't exactly match any of these pictures.
