THE BLADE IS PROBABLY OLDER THAN THE HANDLE. ALL THE INLAY REMINDS ME OF DAYAK MANDAU BLADES SO PERHAPS THE ORIGINAL HANDLE WAS OF THE OLD DAYAK STYLE.
FULLERED BLADES ARE UNUSUAL IN MORO OR DAYAK BLADES SO CUSTOM MADE WITH FULLERS OR FROM A RECYCLED BLADE
INLAY ON KAMPILIAN BLADES IS NOT COMMON BUT QUITE A FEW ARE AROUND. THE INLAY IN YOUR BLADE IS MORE NUMEROUS AND IS NOT ONLY AT THE TIP AS IS USUALY THE CASE. THE STAR SHAPED INLAYS ARE UNIQUE ON KAMPILIANS IN MY EXPERIENCE.
ITS LIKELY INFLUENCED FROM MORE THAN ONE SOURCE, PERHAPS MORO, DAYAK, EUROPEAN, CHINESE OR INDIA. IF IT COULD ONLY TELL ITS STORY.
NICE ONE
