Thanks for the explanation Alan.
Regarding quality.
For example, in the first keris, we can see that the pamor from the pucuk towards mid blade covers the the entire blade width, but towards the sorsoran, there's a section where the pamor does not cover the width evenly. Is this an acceptable feature for a good keris?
Within the limitations of the above photos, what can you say about the quality of the 2 keris we have in this thread (in terms of shape etc) ? Do you think the kembang kacang is properly shaped?
