Robust discussion!
Following Kino's lead, I went off looking for the similar scabbard that has me intrigued. I could not locate one similar within the pages.
The only other ones I recall, one partial hexagonal in the Penn Museum, another in my collection, it though in not as thick as this one looks to be at the base, nor does it have what looks to be a carved protrusion at the end, another in the entourage of Datu Piang, with the additional carry handle,
Some of these others seen that are close but not quite close enough to my eye, are below. Happy to take advice on the nature of these hexagonal types, flaring at the base or not.
I did see this one as a side note, one of Ron's with staple and rope or remains of a munsala.

And another with quite narrow spacing of the holes, rope and munsala only.
