@Contributor: thanks for the Kogarasmuraru's hint, is really hard to classify a nihonto (even historians of such sectors have issues about it).

Doudanuki's school also made tantous among the other types, if I remember correctly. Generally, more danuki's blades would be nice.

Regarding Yasusada's oodachi, it belonged to Nagai Naotsune, a Edo Period's daimyo which controlled various territories. Later, the swords was given to Sada Jinja: a shinto shrine in Matsue, Shimane Prefacture (one of his former territories), hence its name. Recently, it was exposed in Osaka museum, spreading the various fan works about it. I would like its implementation, to be honest, despite the hard feat to find a name to distunguish the two swords.

I noticed that many oodachis belonged to households or shrines, as well some of them being small compared to the 100cm lenght (some of them are in the tachi's category).
