Hi Carlos,
I know byself nearly nothing about panabas, only that I want to have one.
I think that you catch it quite cheap?
What I can see is the upper ring or cap from the handle missing. From which material are the other rings? The wood of the handle seems to have a good patina but the blade looks a little bit crudely worked or is it just from the pictures? Please post better pictures when you have received it.
Best regards,
Detlef
