Symbolism of Bali Cecekahan handle?

[Gustav]

You can find another very interesting "Cekah Redut" (more then eleven notches) in Zonneveld's "Traditional weapons ..." on page 67. It is also polychrome - blue (black?), red and gold(?). This polychrome design looks very fine, somewehere "japanese"

These carvings on one side (five (?) lines). I have seen them only on cecekahan, never bondolan. May be, it is a symbol, bound to a certain group of people, the selected warriors with "Pemating"?

I allways thought, they are another primitive form of a face, but they are on the other side of hilt, and only on cecekahan (?).
