Also i think earth ponys would not really need sword, they have super strength and enhanced durability.
Pegasii and Unicorns could use Wings or Magic to wield swords...
still some Pony would surely go for swords for coolness.
And Pegasii wielding swords with Wing-Hands is a entirly new topic
It might happen sooner than you think. I've got a friend who's done real-life recreations of RWBY weapons, and I could see them trying to re-create this one because they're also a real sucker for Minecraft.
