If you look at the picture of Kirinji that Xilinoc put up, you can see the "paddle" part gripped between his toes. His Zanpakutō is disguised like Yamamoto's inside his walking stick or more like Urahara's in his cane. It seems its Shikai is just that it shines brightly (although this could be a transitional state while it transforms into something else). Of course, that makes the sealed state a kind of pole-arm. Still unique.
