Speaking only for myself I would refer to it as a machine or device; much like the electric chair.
I tend to distrust the large 'Panabi'
that are only wrapped with rattan.
IMO a serious combat weapon of that size would need iron bands to guarantee its integrity in combat. The way panabas blades are mounted in a slotted handle even accounting for the use of strong natural resins and rattan wrap they would be subject to great shearing force at the blade-handle joint.
Resins suitable for a kris would be more challenged by the panabas style of mounting.
