Very large (East?) Javanese Keris for Comments

[Athanase]

For me the notch on the internal face of the Ganja was made during forging to give its domed profile on each side, while starting from a thin piece of metal, in the but to save material.
After that do not say if it is the original Ganja or a replacement.
Originally it was rust welded to the blade, but after a vinegar bath to remove the rust it became free again.
