I think we have come to point where we agree on the answer of the IP's principal question.
We probably agree to (partly) disagree on some other issues, which seem slightly off topic. I dont think its right to have a general discussion about quality in this thread (since we're not longer talking about this keris in particular), so I would propose to leave it here for this specific keris.
In case we're discussing Keris quality measurements and standards in a new thread, I would probably jump in to agree or agree to disagree again
