So should Kimimaru be swordbearing? He creates a "sword" out of his body if you even want to call it that. More like spikes and his spine's a whip. Asuma just uses modified kunai knives and is considered swordbearing. Mangetsu summoned swords from a scroll, but it doesn't seem like he uses a weapon at all on the China server so I can see why he isn't considered swordbearing there.
