Hi Jose,
Here is a link to a previous thread on this style of sword and hilt
http://www.vikingsword.com/vb/showth...ht=head+parang It seems that there are a few variations of these and I'm not sure if it was ever decided exactly where they are from but Batangas was mentioned as a possibility. I know that there were more discussions on these but haven't found the links yet.
