"This is Japanese, not Chinese. There are differences between the meaning/usage of the kanji in the two languages. The predominant meaning of 刀 in Japanese is "sword", "small sword" etc.. Maybe it has the meaning of "blade" in some context, but if no dictionaries that I checked (Denshi Jisho, Weblio Japanese-English, Weblio Japanese-Japanese) list it as a meaning, then such an occurrence should be rather rare." then why is this called as dual blade?
