I'm guessing this forum will be the easiest place to discuss the choices....
From CCOR tab:
I'm just going to leave this here: http://elderscrolls...._Sword_(Skyrim)
I know that the setting says it doesn't effect vanilla weapons, but if it's not lore-friendly I just find it interesting that there is a katana in the vanilla game. I would say that katana would be lore-friendly. The rest, most likely not, though you have to admit that the blade's armor does look a little samurai-ish.
Sorry, this is a copy 'n paste bug. This one should have "needs more research" instead of a definitive no because I'm trying to wrap my head around the Eastern style swords and how they might fit into the game. You do make a good point that the sword used by the Blades closely resembles a katana, but the scimitar used by the Redguard is also an Eastern-style weapon.
Now that I think about it a bit more, I'm wondering if we even care about the Eastern style and fantasy swords? Specifically, (assuming I'm not wrong here) STEP doesn't include any weapons that fit into these two categories so it would be the user's decision whether to include any mods that fit into the Eastern or fantasy styles. Assuming this is the case, these two settings wouldn't necessarily be applicable.
This is just a thought and I'd like to hear what others think about this as well.
