Or they just summon them with Kido like Hachigen does? Or they leave them at home similar to Yoruichi? or Whatever the hell she does with hers? They are the strongest shinigami, maybe they are so strong they have no need to even carry them, to reduce the extra weight etc, i mean, given what we have theorized of their strength, their Hakuda skills are probably sufficient to dispatch almost any enemy. Yamamoto took out Wonderweiss with just Hakuda and Shunpo, and Wonderweiss beat the likes of Kensei and his Bankai. If we think about it, 5 of them surpassed the power of the entire gotei 13, including Yamamoto. They are probably on his level so we could assume that carrying their zanpakuto might affect the spirits in soul society? Or something weird, then again its a friendly visit, carrying a zanpakuto looks like they are ready to fight, which they were not.
