Hey Blu, that's a pretty cool blade.
If you are referring to the keris on pg. 41 of Invincible Kris, i actual find the features on your keris more interesting, especially the "Siva's eyes" thing (there are 2, so i don't think this could be the 3rd eye, but both eyes". Of course the gonjo wilut on that piece is pretty cool too and i think it might be a bit older than yours, but from the photo it is hard to tell if the garap is really that much better. I also find the uneven sogokans very interesting, a feature i have noted on other keris pedang of this type. Does anyone know if there is a practical purpose or spiritual meaning for this?
