Other possibility... It's the quench line.... But i doubt it is.
I honestly grind my mind

Agreed a forge weld of a broken blade would show a scarp joint. Here are two random theories: 1. Stress fracture that opened and was welded (closed) during the forging process? 2. Silver solder of a break?

Bonus idea could the billet have been saw cut and had a sheet of the lighter metal inserted then forge welded together? Either partially cut and then heated or fully cut and upset?
