Philippine Dbl Edge Blade w/Sngl Edge Hilt

[RobT]

Hi All,

Although the hilt and blade are both from the Philippines, I suspect that the hilt and blade were originally on two different knives. There are three reasons that I believe this knife is currently a marriage.
1) The double edged blade is bilaterally symmetrical in profile. The hilt, on the other hand, appears to have been fashioned for a single edge blade. In the Philippines, was a single edge hilt style ever traditionally combined with a symmetrical double edged blade?
2) The tang, although plainly visible at the end of the hilt, isn’t peened over (and there is no washer hilt cap either).
3) The blade is far nicer than the hilt.
Specs:
The asymmetrically ground (flat on one side) blade is 10.375” (26.35cm) long and 1.25” (3.175mm) at the widest point.
The wood hilt has a single circumferential groove at midpoint and an animal face (damaged) on the butt.
The ferrule is brass and the guard is steel.
Any opinions/information/examples will be greatly appreciated.

Sincerely,
RobT
