Hmm, title says it all, we have Kimimaro who uses his bones as a spear & Jinin Akebino who uses a hammer and an axe, both classified as "sword" ninjas.

But this version of Madara who uses a fan and a scythe in the anime isn't a sword ninja, also his Susano'o actually uses swords.

Hmm, Idk if it would make much of a difference playwise, just that you could use him with Midnight Blade + root instead of only Scarlet Blaze with Genjutsu Mirror and Illusion Shield.
