60 grit sand/clean: the tang, inside of the ferule, handle ferule neck.
Use 1/4 or 3/16 4″ (or whatever the tang length) drill bit to clean the tang hole.
Pour 1/6 oz (or more if not enough) of a mixture of 2/3 g/flex epoxy + 1/3 saw dust into tang hole. Coat epoxy inside metal ferule & ferule neck. Insert ferfule & tang. Pour more epoxy into hole if epoxy doesn’t spill out when insert the tang. Clean unwanted epoxy. Place knife vertical for 7hrs before f&f touches.
Stab bend knife tang into a green apple or potato, push apple down into the heel. Heat up the tang over open fire to 400-600F, now bend the tang straight. Hammer tap it if it refuses to straighten by leverage. Make a new hidden tang handle out of hard wood (instead of what the original handle appeared to be very soft wood). Have fun carving ‘bread’.
