Could this be considered a hudiedao ?

[Freddy]

Were these weapons always used in pairs ? I know, when you see them in Wing Chun, there are two. I compare them with the Japanese sai (but hudiedao are sharp !).

But there is a Japanese weapon called a 'jutte'. Mostly a simple iron bar with 1 hook. A weapon also used for parrying and this weapon was used alone.

Just a thought...could certain types of hudiedao be used in the same way ?
