Javanese Keris?

[A. G. Maisey]

I agree with you Jean:- is is accidental, but it did not look like it does now directly after the weld failed. It started as a cold shut, an accident, but it was preserved and improved into a magical blade feature.

The thinking is:- this was given to us by God, who are we to refuse it? no, I won't try to get the weld to take, I will accept God's gift and enhance it.
