Question on tulwar blade construction

[Jens Nordlunde]

To my opinion the scarf welding mostly have been made by an artist, but what Eric shows is a bit more artistic than most of the scarf weldings I have seen.
However in this case the smith does not seem to have been an artist, but we does not know, if he had to do the repair over night as the battle was not finished yet, and had to go on the next day.
