Pihiya Kaetta - any ideas about age?

[ingelred]

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):
