There's also a
Lumad sword
posted a long time ago which hilt is similar.
This Lumad sword's blade looks like a Visayan ginunting, however. Thus perhaps the sword originated from Panay, and was just dressed up later by the Lumad who got it.
In summary, the unusual hilt (i.e., with bulging 'eyes' to its left and right) looks like it's really Visayan.
