Well, when we were running from Tokei it was described to be 2 feet long. Here's the relevant quote...
Officially a sword of that length would be considered a wakizashi.
Not really? The cut-off mark for the difference between an o-wakizashi and a katana was a total length of 2-
shaku (roughly 60 cm). So, the Sword of the Watchman would likely be right on the border of that definition; any shorter and it is an O-wakizashi, any longer and it is a katana.
But... Is it not possible that that "2-foot" length was referring to the blade/sheathe? At which point it would just be a katana.
The description fits that of a katana quite well, it has also been mentioned that it has some curve to it. A katana can be used both two-handed and one-handed although primarily the former. Mifune, the samurai general uses a katana and the normal soldiers uses something that looks akin to a wakizashi.
That description also fits the Yanmaodao too, but that's a digression on preference. The yanmadao's
really similar to the katana in form, only slight differences in the blade's tip-shape allowing for ease of thrusting strikes in addition to superior cutting ability.
Still, considering that Tokei was skilled and high-ranked enough to be distinguished for the duty of watching over Daisuke and Manami, and the the sword is really beautiful, it obviously wasn't an ordinary soldier's blade. So it's likely that the Sword of the Watchman might be a
Meito, like Mifune's own sword, Kurosawa.
I mean, just based off of the description Ves gave, it's clear that this is no mere samurai sword - the craftsmanship and artistry involved means it's definitely a 'named sword' with a history.
