1/2 + 1/2 makes 1?

[sirek]

After removing a thick layer of rust, there appears a keris made of two pieces?

After cleaning, some questions came to my mind:
Was it done because someone appreciates the "pusaka" value of one half?
Or imho. this was made of two different broken pieces, and becomes a commercial keris.

But still, is it not difficult (and expensive) to forge two distinct halves together?

I would like to hear if anyone knows about these fabrications / repairs.

Thank you in advance,
