carlos, nice find! when will my turn come?
cabatuan is a town in panay island which is known for good smiths. i saw one antique sword in panay made by a cabatuan smith that used albino carabao horn for hilt. the guard of your sword looks like it's made of albino carabao horn as well.
the carving of the figural monster looks not the usual though. but that makes that piece unique in its own way. congrats!
