That looks very much like someone heated a spot on the edge, either to straighten a deformation, or in attempt to re-harden a spot.

Highly likely.
European bladesmiths of the 19 century got plenty of wootz ingots and forged them into blades using European custom of heating the ingot to “ white”. Surprisingly ( for them) the beautiful wootz ingots produced boring monosteel blades:-) Now we know why: at temperatures above ~850C dendritic structure just melts away and there is no way to restore it. That raises another question: how did Persian or Indian masters managed to forge together 2 different samples of wootz to create scarf welding with only a thin line of amorphous steel as a scar? |
