One pair of katanas in the game?

[Tupsi]

This does make a fair bit of sense, if you think about it.

Then you remember, using lore, that they never explained why Arcanist went from Trap users that used Mechanical staves and automatons to suddenly becoming summoners, as well as why we suddenly have daggers being sold everywhere when they weren't before. A lot of items we have access to aren't native to eorzea either, but yet here they are.
