Ivory hilt dagger with "Tears" and a "Smiley?"

Hello Gene,

Just as an aside: the magnetic field seems to follow the blades curve - is it possible that the (relatively) low forging temperature of wootz allows an original ingot to remain magnetized? That still wouldn't explain the reversal though!

I know that a magnetized steel needle becomes depolarized when heated to glowing red - what about dendritic steel though? Need to pull out my compass and test another recurved blade...

Regards,
Kai
