Hello, 
I recently acquired this Pihiya Kaetta style knife at ebay. 
Or at least I think it is a kind of Pihiya. 
The handle reminds me of the Serapendiya hilted Pihiyas altough the handle is made of cast brass. 
It is looks like a working type of knife than the commonly found highly decorated Pihiyas. 
Do You have any ideas if this could be a predecessor of or a working Pihiya contemporary to the highly decorated Pihiya Kaetta?    
Here ist the link to the knife (ebay No.: 390058685768):
