To my knowlegde, the Widmanstatten structure disappeares at a temperature of about or some over 700 degrees C.
The materials for forging the dagger are too cold to forgeweld at that temperature.
Widmanstatten structures are formed by extremely slow cooling of the material during millions of years.
So the meteoritic material has been inserted in te dagger cold, or at least on a temperature lower than 700 degrees C.
