Hello. I have a newbie question about kampilans

Though I've had the pleasure of handling ginuntings, pinutes, keris, and talibons, my experience with kampilans has been nonexistent.

Which is the sharp side on a kampilan? Is it the side with the barb/hook, or the opposite side? Or are they double-edged. I thought I could tell by the orientation of the "crocodile jaws" handle, but I've seen the "jaws" facing both sides of the blades in kampilan pictures.

Also, does anyone know if it's true that small brass discs embedded in the blade are representative of how many enemies that enemy has killed?

Thanks,
