Sword I.D. Help Needed

[Clubs & Arrows]

Hello,
I picked up this sword in a collection recently, and was wondering if anyone in the forum could help me with it's origin. The overall length is 39 1/4" , with the blade accounting for 31 3/4" of the length. I can't find any marking on the piece at all. The leather covering over the wooden grip has seen better days. I collect Pacific Island weapons, so this is a little out of my range of collecting.

Thank you,
Joe
