What Weapon Should A Blue Mage Use?

[Cidel]

Blue Mage was introduced first in 5 and they can use swords. Scimitars and sabers are techincally swords.

Summoners weren't introduced into the series (to my understanding) "wielding" grimoires either. Bards weren't commonly associated with wielding bows.

"Technically" DRKs, RDMs, SAMs and PLDs all wield swords but the type of sword and shape varies. I do concede though that scimitars and sabers can be too visually similar to PLD's main arm (a handful of their weapons already look like scimitars) so I would think the devs would opt out designing a new job with a weapon-type that's already represented. So unless it's an easily distinguishable new type of "sword," I don't see that as a weapon for a new anything.
