No Penangsang, you don't bore me.
I think I now understand where you're coming from, and it seems that we are travelling in different directions.
Thank you for expanding your comments.
Thanks Pak Ganja.
It won't be a shrink fit if a pin or key has been used.
It will be a press fit, ie, cut to a very neat fit, but not requiring heat to put in place over the pesi.
If you use a pin after a shrink fit, you actually run the risk of weakening the joint.
Looking at the image, it does look as if iron filings and epoxy, or maybe plastic steel has been used to fill, but you you say this is not the case, OK, its not. But I can't help wondering how the black material that fills the gap between blade and ganja has finished as it has at the tungkakan. Fascinating.
A ganja can build up corrosion in a very short period of time, and under some circamstances, this can bind the ganja to the pesi.
