Chinese (or other country) sai/parrying weapon

[Shakethetrees]

I've been struggling with this one for a long time.

It's entirely hand wrought iron and I would have no problem assigning an 18th/19th century date.

I'm sure the grip was wrapped at one time.

Any information y'all have will be appreciated, nationality, an accurate name for it, etc.

I suspect it's a KungFu or other discipline weapon, but I'm open to suggestions.
