From what I can see, I would give this as Lawe Setukal.

There are many variations of Lawe Setukal.

I have seen something like this named as Untuk Banyu, I think Tammens gives Unthuk Banyu as similar to this.

The other pamor in the center of the base I'd probably give as Sombro.

Would a close up in decent light be possible Anthony?

I'd like to see how the grain of the pamor winds back & forth, the way in which it winds could indicate whether it was intended to be lawe or unthuk.

Edit

I just added the pic. I'm inclined to think it was intended as lawe, but the outside of the bend in the material has been lost. This material in the pamor was turned at 90 degrees to the blade core & then twisted backwards and forth to create the effect of a series of bends.

Unthuk banyu should not be as regular as this, the bends are created laying the strip of material as mlumah and bending away from and then back to the core, and it might be twisted first before the bending is done.

With lawe the strip of material is oriented miring and bent away from the centre of the blade & then back towards the center.
