Kikik added to an older blade?

[Bjorn]

Hello all,

I have a small keris with a kikik, which I recently cleaned. After cleaning, I noticed a line going across the sorsoran, starting at the neck of the kikik and then cutting across the sokogan depan. This line is found on both sides of the blade.

Does this mean that the blade has been altered in some way? Perhaps to add a kikik to a blade that originally didn't have one?

Apologies for the poor photos, I took them in sub-optimal lighting conditions with my cell phone, but I hope they're enough to convey the meaning of my query.
