Hello Tom,
Both stick have similar dimensions: 4mm wide, 2mm high, 95mm long, rectangular cross-section. They are made of wood. The binding looks like hemp and it is/was covered with tar/pitch of some sort. It appears like the sticks were also painted with pitch.
I'm not so sure about the edge alignment theory. While i have no idea how moro martial art looked/looks like, i personally would hold the kris with my thumb resting on the broad side of the blade base for better control. This would provide more than enough edge alignment regardless of hilt geometry
Best Regards,
Thilo
