Unknown Philippine weapon, cane cutter ??

[drac2k]

I recently purchased this item and I guessing that it is from the Philippines.The blade measures approx. 12.25 " and it is wider than 2 " at it's greatest width.The ferrule appears to be ivory or bone. The scabbard is comprised of 2 pieces held together, not by nails, but wooden or bone dowel pins.I would guess the age to be from WW2 to the early 1960's.
Any opinions would be appreciated.
