Forunately we have an oven with gas (propane or whatever it is that comes from beneath the surface of our country.)
There is a very small flame for preparing lovely tender beef dishes like rendang
This same flame was perfect for slowely heating the blade.
Tried it 3 times, but not the smallest movement.
Indeed I hold the blade wrapped with some cloth to keep a good grip and still have feeling with the material.
As there was no movement at all, I will not try to force it and poored 2 drops of oils into the pendokok and will let it lay for a while.
Will try to place some better pictures of the hilt this afternoon
