Thoughts on this Keris

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.

Spot on Seerp. Jerzy said pretty much the same thing about ID of meteorite after the forge weld process.

It is a really pretty keris David, in fact much better than the photo shows, that photo was done more than ten years ago, my equipment and understanding has improved a bit during the last 10 or 12 years.

As for our young wouldbe blade smith, I'd just as soon not comment, let other people teach him what's right & what's wrong.
