long chinese dadao execution ''sword'' ?

[francantolin]

Hello everybody ( And Happy New Year 2020 !!!)

I picked up this long and large sword-polearm in France in a flea market
more than 110cm long half for the blade, half for the handle.
really sharp blade, the back side of the blade is almost 1cm thick...

( not easy to walk with in the street even wrapped with plastic bags.. )

Do you think this model is chinese ? ( maybe vietnamese ? ( guard type ?)

I still havent clean the blade, it seems laminated steel.

Do you think that the band-rope is a later replacement ?
It's not really well made so
I hesitate to take it off and change it...

I wonder why the handle is so long: too long for a sword,
short for a polearm...
an usual shape ?

What do you think ?

Thank you
