Methuk To Mendak

[Rick]

The Keris Buda I have seen have a separate Gonjo topped off with a Methuk (for the most part) as is seen in many Tombak .

Can we accept that this was a common early form of securing the Gonjo to the Wilah ?

I wonder; if this is so; at what time or era did the Mendak start to replace the Methuk in the development timeline of the keris in Jawa ?
