unknown asymmetric spear to identify

[abeek]

Hello Members

I found this strange asymmetric spear with even a asymmetric end

It is 190 cm long with a hardwooden shaft from thin to thick

thanks for the help, Aart

I forgot,

the total lenght of the head is 33,5 cm the but is 10 cm

I would take a wild guess of South East Asia due to the construction of both ends.
