keris made by empu(forged) and keris made from moulding

[Timo Nieminen]

In principle, you can do pamor (or at least its approximate appearance) on a cast blade. Inlaying after casting, or casting with inserts come to mind as possible methods.

(I see fake Chinese bronze castings with patterns. Easier to do with bronze (probably brass rather than bronze) than with iron/steel.)
