Ganja iras
 

Greetings to all keris enthusiasts. In your opinion, does the ganja that forms a single whole with the keris blade (ganja iras) carry any special meaning or indicate certain features of the keris? Here I mean:

an indication of a particular period style (tanggu)

the area of use, e.g., a combat keris

a regional characteristic (more common in some places, less so in others)

a specific feature of a certain group of Empu, for example, rural ones — not associated with the keraton

some sacred meaning. Let me clarify my thought: the ganja was symbolically considered the ‘female’ element, while the blade was the ‘male’ element;
their union had a ritual-cosmological significance.
When a ganja iras is made, the boundary between these two principles disappears — everything becomes a single whole.
