Twistcore Padsumbalin?

I do see the limited irregularities which (IMHO) seem to have been introduced inadvertantly during the forging process

I should rephrase my comment above: The single lamination layer with the row of blotches shows enough regularity (as well as plenty of cold shuts not visible throughout the other layers) to assume that it was introduced on purpose by the bladesmith. However, it doesn't appear to be such a strikingly visible pattern that I'd be convinced that this was intended to be a showy lamination pattern. If anything it bears limited semblance with the blotchy pamor seen in some barung; however, the latter is usually pretty much irregular.
