Javanese keris / reshaped or not.

[asomotif]

Dear Rick,

Yes I realise that smoothing out the edges could have been a good reason.
But in its present state the blade has a set of "shoulders".
I wonder if this is something that is good craftsmanship, or maybe this set of shoulders is not OK ?

I have tried to give my impression in drawing of wrong (red) and right(green).
As you can see, I am a total dummy with the "paint" program.
