Has anyone made a study of the marks often seen on these blades some call fingerprints. I am speaking of the deliberate indentations made along the blade of such keris. Specifically I want to know if the number of indentations follows numeric rules (like the luk in keris) such as always being an odd number or if some numbers are seen more then others such a 3 or 7 also if older ones tend to have a number that differs from later ones eg fewer or more indents.

The oldest wavy sajen keris I have seen have all been 3 luk blades, would be interesting to see if the oldest straight bladed keris sajen tend to have three indents along the length of the blade.

I know some are going to say these indents are the result of shrinkage whilst cooling, I personally don't believe that, I think they are deliberate markings.
